Johannes Kepler was a German astronomer who is best known for his three laws on planetary motion. He lived from 1571-1630, and his works all took place during the scientific revolution (Johannes Kepler). He was most famous for coming up with his three laws of planetary motion. His first law states that all planets move in an elliptical orbit with two foci, one of those foci being a star. His second law states that if one was to connect a line from a star to a planet, at equal times, they would sweep out equal areas; which show that the overall energy is conserved (Kepler's Laws).
The third law states a mathematical relationship between the period of a planet and the radius of its axis.
Mathematically it states that, where k is a constant for a specific solar system.

When compared to the actual value there is a percent difference of 1.3%. But if both figures were to be rounded to 2 significant digits than the percent difference would be 0%. Using this constant, the period or the axis radius of any stellar object orbiting the Sun can be found.
When looking at Graph 1, it can be seen that the relationship between the period and radius of a planet's axis is exponential. The further the planet is, the longer its period is. When looking at Graph 2, it can be seen that there is a y-intercept.
This is probably occurred because such large distances were used, and when calculating the data, some figures where rounded down, thus giving a y-intercept. It can also be seen that there is clearly a linear relationship between and , which verifies that Kepler's 3rd law is indeed true.
Simple pendulum, consist of a metallic bob, suspended by inextensible string from a rigid support .At the mean position, when the bob is at rest there is only gravitational force (g) acting on the bob this kept it at rest. When the horizontal force is applied on the bob then it moves towards its extreme position .From the extreme position it moves back to its mean position and move further to the extreme position on the other side and again back to its main position, this motion of simple pendulum, that is starting from mean position and back to it is known as ONE CYCLE.
Amplitude: It is the distance between the two extreme positions. Aspect 1: From the above data and results we have concluded that there is an impact on the frequency of a simple pendulum if changes its length and there is no effect on the change of mass and amplitude. To be very cised there is a slight effect on a change on the mass or amplitude but it is quiet negligible that's why we do not consider them. Aspect 2: Due to the presence of air there might be some error introduce in the experiment so take necessary precaution to minimize the error. There is possibility that while taking different readings the length of thread might be measured incorrectly, so make a mark on the thread to avoid any error.
