Aball 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.
its potential energy increases, and its kinetic energy decreases.
b.
its potential energy decreases, and its kinetic energy increases.
c.
both its potential energy and its kinetic energy increase.
d.
both its potential energy and its kinetic energy decrease.
