(4) Purpose
The purpose of this experiment is to show that the kinetic energy of a ball launched straight up is transformed into potential energy.
(5) Theory
The total mechanical energy of a ball is the sum of its potential energy and its kinetic energy. In the absence of friction, total energy is conserved. When a ball is launched straight up, the initial PE is defined zero and the KE=. where m is the mass of the ball and v0 is the muzzle speed of the ball. When the ball reaches its maximum height h, the final KE is zero and the PE=mgh. where g is the acceleration due to gravity. Conservation of energy gives that the initial KE is equal to the final PE.
