Question

fill in the blank (energy and momentum unit)

A ball falls to the floor. As it falls, kinetic energy ___ and gravitational potential energy ___

Answer 1

From the equation,\[K=\frac{1}{2}mv^2\]as the ball will fall down it's velocity will increase gradually hence it's Kinetic Energy will increase. While that in potential energy\[U=mgh\]hence with decrease in height of the ball, it's Potential energy will decrease
