Confirming Kepler’s 3rd Law Lab                Adnan Masood



        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,

    The trend for manipulating the spinning mass is also inversely proportional to the frequency of that motion. As the mass increases, the general frequency will decrease. The following suggests the percentage error for the spinning mass experiment: Spinning Mass: Theoretical slope = 0.0667; Experimental slope = 0.0491 This is also a relatively intense error.

    This was due to the fact that the spring was not on a flat surface, and, instead, suspended in the air. Therefore, the ruler had to be held beside the spring by a person but could not actually touch the spring as this would affect the force sensor's results.

So,its not accomplished to the KCL.This is because current in is not equal to current Out.
