Sounds of Kepler's Law
Kepler's Law 1
Kepler's Law 1 is known as the law of elliptical trajectories. Kepler's Law I reads:
"All the planets move in an elliptical path around the sun with the sun in one of the elliptical foci"
Kepler's Law I states the shape of the planet's orbit, but cannot estimate the position of the planet at any one time. Therefore, Kepler tried to solve the problem, which subsequently succeeded in finding Kepler's II Law.
Kepler's Law 2
Kepler's Law 2 discusses the planetary motion which reads as follows.
"An imaginary gads that connect the sun with the planet sweep across the same wide area at the same time interval"
In the same time interval, Ll, Lii, and Liii. from Kepler's II law it can be seen that the speed of the biggest planetary revolution when the planet is closest to the sun (perihelium). Conversely, the smallest planet's velocity when the planet is at its furthest point (aphelium).
Kepler's Law 3
In this law Kepler describes the revolutionary period of each planet that surrounds the sun. Kepler III's Law reads:
The square period of a planet is proportional to the square of its average distance from the Sun.
Mathematically Kepler's Law can be written as follows:
Information :
T1 = Period of the first planet
T2 = Period of the second planet
r1 = distance of the first planet from the sun
r2 = distance of the second planet from the sun
This equation can be derived by combining 2 Newton's law equations, namely Newton's law of gravity and Newton's second law for regular circular motion. Decreasing the formula is as follows:
Newton II Law Equation:
Information :
m = the mass of the planet that surrounds the sun
a = centripetal acceleration of the planet
v = the average speed of the planet
r = the average distance of the planet from the sun
The equation of Newton's law of gravity:
Information :
Fg = Sun's gravitational force
m1 = mass of the sun
m2 = planet's mass
r = average distance of the planet and sun
Supporting Articles: Definition, Formula and Application of the Law of Gravity
Combined the two formulas above so that it becomes:
m2 on the left and m on the right are the mass of the planet so they can be removed.
The length of the path the planet is traveling around the planet's orbital path. The circumference of the planet's orbit can be formulated with 2 x phi x r, where r is the average distance of the planet from the sun. It is known that the average velocity of the planet is the ratio between the circumference of the orbit and the panet period, so that:
The constant k = T2 / r3 also obtained by Kepler was found by means of calculations using Tycho Brahe astronomical data. The results are also the same as those obtained using Newton's second formula above.
Examples of Kepler's Legal Questions
The time required by the earth to circle the sun is 1 year and the average distance between the earth and the center of the solar system is 1.5 x 1011 m. If it is known that the planet's orbital period of Venus is 0.615 years, what is the distance between the sun and Venus?
Known :
Earth period = Tb = 1 year
The distance from the sun to the earth Rm-b = 1.5 x 1011 m
Venus period = Tv = 0.615 years
Asked
Rm-v = ...?
Answer:
example-matter-law clerk-iii
So by using the law of Kepler III the answer is obtained the distance between the sun and the planet Venus is 1,084 x 1011 m (closer than Earth).
Understanding Kepler's Law
Understanding Kepler's Law
Kepler's Law was discovered by a mathematician who was also a German astronomer named Johannes Kepler (1571-1630). His discovery was based on data observed by Tycho Brahe (1546-1601), a famous astronomer from Denmark.
Before the discovery of this law, ancient humans embraced geocentric understanding, which is an understanding that justifies that the earth is the center of the universe. This assumption is based on limited human sensory experience, which is every day
watching the sun, moon and stars move, while the earth feels silent. This assumption was developed by the Greek astronomer Claudius Ptolemy (100-170 AD) and survived for up to 1400 years. According to him, the earth is at the center of the solar system. The sun and planets circle the earth in a circular path.
Then in 1543, a Polish astronomer named Nicolaus Copernicus (1473-1543) invented the heliocentric model. Heliocentric means that the earth and other planets surround the sun in a circular path.
Of course this opinion is better than the previous opinion. However, there is something still lacking from Copernicus's opinion that silence still uses circles as a form of trajectory of planetary motion.
In 1596 Kepler published his first book in the field of astronomy with the title The Mystery of the Universe. In that book he explained the shortcomings of the two models above namely there is no harmony between the trajectories of planetary orbits with observational data of Tycho Brahe.
Therefore Kepler left the Copernican model as well as Ptolemy and sought a new model. It was only in 1609 that an orbital shape was found that matched Brahe's observational data, the elliptical shape. Then his findings were published in his book entitled Astronomia Nova which was also accompanied by his second law. While Kepler's third law is written in Harmonices Mundi, published ten years later.
The Function of Kepler's Law
The function of Kepler's law in modern life is to estimate the trajectories of planets or other space objects orbiting the Sun such as asteroids or outer planets that have not been discovered during Kepler's life. This law also applies to other orbitals besides the sun.
Like the moon orbiting the earth. Even today, using the basis of Kepler's law, a new object orbiting the earth is found besides the moon. This object is an asteroid measuring 490 feet (150 meters) dubbed the 2014 Asteroid OL339.
Asteroids are close enough to the earth that they look like satellites. The asteroid has an elliptical orbit. It takes 364.92 days to circle the Sun. Almost the same as the earth which has a period of 365.25 days.

Kepler's Law 1 2 3: History, Sound, Function and Formulas
Kepler's Law 1 2 3: History, Sound, Function, Formulas and Examples of Complete Questions - Kepler's Law was discovered by a mathematician who was also a German astronomer named Johannes Kepler (1571-1630). His discovery was based on data observed by Tycho Brahe (1546-1601), a famous astronomer from Denmark.
The History of Kepler's Law
Inventor Biography
Johannes Kepler was born on December 27, 1571 in Weil derstadt Germany, he was an important figure in the scientific revolution, and a German astronomer, mathematician and astrologer. he is best known for the laws of planetary motion. He died in 1630 November 15 in Regensburg Barvana-Germany.
Kepler grew up in a state of many problems. His aunt was burned accused of being a witch. And her mother almost had the same fate. This child is often ill and has poor eyesight that cannot be corrected with glasses.
Since childhood he had often been acquainted with the symptoms of the sky and celestial bodies. In 1577 he and his mother witnessed the appearance of a comet. And in 1580 with his father he witnessed a solar eclipse.
Kepler was so smart that he got a scholarship to study at the University of Tüũbingen to study theology, philosophy and mathematics. He taught mathematics and the basics of astronomy at the University of Graz in Austria. In 1584 he entered the Adelberg seminar to attend school. And in 1588 he obtained a full bachelor's degree.
Background to the Discovery of Kepler's Law
His discovery began in 1597, at which time he took the position of assistant to Tycho Brahe at the Benatek Observatory, Prague, a famous German astronomer.
When Tycho died in 1601, he left his notes and planetary reading tables to Kepler and Kepler replacing his position as Head of the Observatory and royal mathematician.
Instead of Tycho Brahe, Kepler inherited a large pile of records of careful observations of the planets Tycho had worked on for years. Because Tycho - the last large astronomer before the discovery of the telescope - was also a careful and meticulous observer that the world had ever known, the records were extremely large.
Kepler believes that Tycho's careful mathematical analysis notes allowed him to draw the conclusion that the theory of planetary motion was correct: Copernican heliocentric theory; the older Ptolemy's geocentric theory; or even the third theory that Tycho himself formulated. But after years of careful calculations, Kepler discovered that Tycho's observations were not consistent with any theories!
Finally Kepler realized that the problem was: he, like Copernicus and Tycho Brahe and all classical astronomers had guessed that planetary orbits consisted of circles or a combination of circles. However, the reality shows that planetary orbits are not circular, but rather oval, ellipses.
Even after finding the ultimate solution, Kepler still had to spend months immersing himself in the laborious and tedious work of calculating to ensure that his theory satisfied Tycho's observations. And finally he published his big book, Astronomia Nova, published in 1609.

Regarding the Change in the Form of Substances by Heat
Regarding the Change in the Form of Substances by Heat
In physics every thing that has a mass and occupies a space is called a substance. And if that has no mass but occupies space, then it belongs to an energy. Which includes those that have no mass such as sound and light. So, in physics that actually concerns the matter of matter and energy. But this time it was discussed about the problem of the substance's form and its changes, the shape of the substance can change due to the heat given or released.
Substance Change
In physics the basic theory of matter is divided into 3 forms, namely:
Solid
Liquid
And gas substances
In science physics, the basic theory of matter explains that matter can undergo a change in form. In solid substances that can change their form into liquid this is usually called melting. Among these, like chunks, ice can turn into water. Then the water can be turned into steam which is called the evaporating event. Which includes events such as the evaporation of water on the surface of the earth into water vapor in the clouds. The opposite of changing the form above is to condense and freeze. The occurrence of water vapor conditions in the sky can experience the occurrence of this condensation because of the presence of dew that is attached / attached to any object or plant in the morning.
There is also an event of change in form which does not undergo a process of melting but instead directly becomes steam, this event is called by flooding such as mothballs turning directly into steam. The reverse process is called crystallizing in which camphor lime can transform into a camphor crystal.
Effect of Heat Against Substance
Heat can increase the temperature of a substance that affects the change in the form of a substance. Melting and evaporating which is an event that requires heat, because to be able to melt a lump of ice or to evaporate water requires heat.
But the event of condensation and freezing does not require heat but releases it, the occurrence of dew forming in the morning is an example of the change in form that releases heat. Likewise the freezing event will release a number of heat so that the water freezes to form a lump of ice.
Like a refrigerator (refrigerator) is the application of the occurrence of changes in the form of liquid substances that become solid, a tool functioned to remove the heat in the water. So thus chunks of ice can form in the refrigerator because the heat in the water has been removed by the device.
So it can be concluded that the substance that changes the substance is caused by the heat, in such a process the heat is needed by the substance to change its form, but some do not need the heat alias released.
Thus the language about the matter of Substance Changes by Kalor hopefully with the review can add insight and knowledge, thank you very much for visiting

Definition, Characteristics and Formulas of Regular Straight Motion
Definition, Characteristics, and Formulas of Irregular Straight Motion and Its Examples in Complete - On previous occasions we have discussed about Irregularly Changing Straight Motion (GLBB) and on this occasion here will review about Irregular Straight Motion (GLB) in full. Therefore, let us consider the review below.
Definition of Regular Straight Motion (GLB)
GLB is as a motion of an object with a fixed speed. Speed is fixed which means either large or fixed direction. For example, a car moves at a fixed speed of 80 km / hour. Which means, the car can travel a distance of 80 km in 1 hour. When the speedometer needle in the car still shows 80 km / hour, which means the car is moving at a constant speed, because the speed of a fixed object, then the word speed can be replaced with speed.
The velocity at GLB is determined by the following equation:
Information:
v = average speed (m / s)
s = total mileage (m)
t = time lapse (s)
Characteristics of Regular Straight Motion (GLB)
An object is said to be moving in a straight line if it shows the following characteristics:
On a path in the form of a straight line or can still be considered as a straight line
At a fixed or constant speed of an object
Has no acceleration (a = 0)
At the length of the trajectory traveled is equal to the area of the v-vs-t graph
At speed is directly proportional to displacement and inversely proportional to time.
Regular Straight Motion Formula (GLB)
S = v x t
V = s / t
Information:
V = speed
s = distance
t = time
Example questions about Regular Straight Motion (GLB)
Ari ran 60 meters in 10 s. How big is Andi's running speed ??
Settlement;
Known: s = 60 m
t = 10 s
Asked: v = ..?
Answer: v = s / t
= 60 m / 10 s
= 6 ms-1
So, the speed of Andi 60 ms-1.
That's a review of the Definition, Characteristics, and Formulas of Irregular Straight Motion along with Complete Examples. Hopefully what is reviewed above is useful for the reader. That is all and thank you.

Complete Understanding, Formulas and Examples of Swipe - Hi Indonesian students meet again with gurupendukasi.com. On the previous occasion I have discussed gravity, and on this occasion here will be a complete review of the friction force. Therefore, let us consider the review below.
Understanding the Swipe Style
Friction is a force that is directed against the motion of objects or the direction of the tendency of moving objects. Friction occurs when two objects touch. The objects referred to here do not have to be solid, but can also be liquid, or gas.
In accordance with Newton's first law, the wooden blocks located on the table work the normal force in the opposite direction to the gravity. If the direction of motion of a horizontal object, the magnitude of the normal force (N) is equal to the weight of the object (w).
When a wooden block is pulled by a rope, a certain amount of force is required. This is due to the frictional force between the surface of the beam and the surface of the table in the opposite direction to the direction of the beam's motion.
The amount of friction is influenced by the weight of the object and the roughness of the surfaces that touch each other. For slippery surfaces, the effect of frictional force is very small, it can even be said to be non-existent.
The friction force (Fg) that occurs when an object has not moved is called the static friction force (Fs), while the friction force that occurs after a moving object is called the kinetic friction force (Fk).
As the wooden block is stretched, the spring balance gradually shows an increasingly large number. This happens because the static frictional force has a number that varies from zero to a certain maximum value. The largest number is reached just before the wooden block moves. This number is called the maximum static friction force.
Swipe Style Formula
In the static friction force the equation applies
Fs = μs N
Information:
Fs = static friction
μs = coefficient of static friction
N = normal force
In the kinetic friction force, the equation applies
Fk = μk N
Information:
Fk = kinetic friction
μk = coefficient of kinetic friction
N = normal force
μk <μs
Fg = Fs or Fk
the magnitude of the kinetic friction coefficient is fixed
Example of a Swipe Style Problem
An object whose mass is 50 kg is on a flat plane. On objects, the force acting 200 N is horizontal. What is the acceleration on the object if
a. slippery field;
b. rough field with a coefficient of friction = 0.3 (g = 10 m / s2)?
Discussion
Known:
m = 50 kg
μ = 0.3
F = 200 N
g = 10 m / s2
Asked:
a. the acceleration of the object if the plane is slippery = ...?
b. the acceleration of an object if the rough field (μ = 0.3) = ...?
Answer:
a. Slippery field
F = m a then a = F / m
= 200/50
= 4 m / s
So, acceleration if the slippery plane = 4 m / s2.
b. Rough field (μ = 0.3)
N = w
= mg
= 50 x 10 = 500 N
Fgesek = μ N
= 0.3 x 500
= 150 N
Ftotal = F - Fgesek
= 200 150
= 50 N
a = Ttotal / m
= 50/50
= 1 m / s
So, acceleration if the rough field = 1 m / s2.

Answer:
a. Slippery field
F = m a then a = F / m
= 200/50
= 4 m / s
So, acceleration if the slippery plane = 4 m / s2.
b. Rough field (μ = 0.3)
N = w
= mg
= 50 x 10 = 500 N
Fgesek = μ N
= 0.3 x 500
= 150 N
Ftotal = F - Fgesek
= 200 150
= 50 N
a = Ttotal / m
= 50/50
= 1 m / s
So, acceleration if the rough field = 1 m / s2.

Lorentz Style Understanding And Formulas
Lorentz Style Understanding And Formulas
Understanding, and Lorentz Style Formulas With Complete Examples - Style ??? In physics there are so many kinds of styles, one of Lorentz's styles and on this occasion here will be a complete review of Lorentz's style. Therefore, let us consider the review below.
Understanding Lorentz Style
Lorentz is the name of a style in modern physics taken from the last name of a physicist born in the Dutch Arnhem named Hendrik Anton Lorentz. The physicist from the country of windmills researched about a current conductor interaction placed in a magnetic field. And the result he managed to find a style which was then called the Lorentz style. This style is then much useful for moving electric motors for various purposes such as fans, blenders, and so forth.
Determining Lorentz Style Direction
In various applications of physics problems we often ask the direction of Lorentz's force. To determine the direction of Lorentz force we can use two alternative methods / rules namely the right hand rule or the screw rotational rule. Look like the picture below below !!!
Lorentz's force is proportional to the strength of the magnetic field, electric current, and the length of the wire. If the position of force, magnetic field strength and electric current are perpendicular to each other, then the magnitude of the Lorentz force can be formulated as shown below.
Lorentz Style Formulas
Florentz = B I l sin α
Information :
B = magnetic field strength (Tesla)
I = strong current flowing in the wire (amperes)
l = wire length (meters)
α = angle formed by B and I
Example of the Lorentz Style Problem
A 4 m long wire is electrified by 25 A. The wire is under the influence of a magnetic field of 0.06 Telsa forming an angle of 30º. against wire. It depends on the Lorentz force acting on the wire ie ???
a.0,5 N c.0,6 N d.0,75 N
b. 3 N d. 1 N
Answer:
Known
l = 4m
I = 25 A
B = 0.06 T
α = 30o
FL = B I l sin α
FL = 0.06. 25. 4. sin 30º
FL = 3 N
So the magnitude of Lorentz force that occurs is 3 N.
Understanding, and Lorentz Style Formulas With Complete Examples - Style ??? In physics there are so many kinds of styles, one of Lorentz's styles and on this occasion here will be a complete review of Lorentz's style. Therefore, let us consider the review below.
Understanding Lorentz Style
Lorentz is the name of a style in modern physics taken from the last name of a physicist born in the Dutch Arnhem named Hendrik Anton Lorentz. The physicist from the country of windmills researched about a current conductor interaction placed in a magnetic field. And the result he managed to find a style which was then called the Lorentz style. This style is then much useful for moving electric motors for various purposes such as fans, blenders, and so forth.
Determining Lorentz Style Direction
In various applications of physics problems we often ask the direction of Lorentz's force. To determine the direction of Lorentz force we can use two alternative methods / rules namely the right hand rule or the screw rotational rule. Look like the picture below below !!!
Lorentz's force is proportional to the strength of the magnetic field, electric current, and the length of the wire. If the position of force, magnetic field strength and electric current are perpendicular to each other, then the magnitude of the Lorentz force can be formulated as shown below.
Lorentz Style Formulas
Florentz = B I l sin α
Information :
B = magnetic field strength (Tesla)
I = strong current flowing in the wire (amperes)
l = wire length (meters)
α = angle formed by B and I
Example of the Lorentz Style Problem
A 4 m long wire is electrified by 25 A. The wire is under the influence of a magnetic field of 0.06 Telsa forming an angle of 30º. against wire. It depends on the Lorentz force acting on the wire ie ???
a.0,5 N c.0,6 N d.0,75 N
b. 3 N d. 1 N
Answer:
Known
l = 4m
I = 25 A
B = 0.06 T
α = 30o
FL = B I l sin α
FL = 0.06. 25. 4. sin 30º
FL = 3 N
So the magnitude of Lorentz force that occurs is 3 N.
