A ball sitting on the top of a table has potential energy but no kinetic energy.
How do potential and kinetic energy change as the ball falls off the table to the floor?
A.
Both its potential energy and its kinetic energy decrease.
B.
Both its potential energy and its kinetic energy increase.
C.
Its potential energy decreases, and its kinetic energy increases.
D.
Its potential energy increases, and its kinetic energy decreases.
