Question

Which scenario shows an object gaining potential energy and losing kinetic energy?
A. roller-coaster car stopped while it picks up passengers
B. roller-coaster car slowing to a stop to pick up passengers
C. roller-coaster car slowing as it moves up a hill
D. roller-coaster car accelerating as it moves down a hill

Answer 1

The scenario that shows an object gaining potential energy and losing kinetic energy is:

**C. roller-coaster car slowing as it moves up a hill.**

In this case, as the roller-coaster car ascends the hill, it gains height, which increases its gravitational potential energy. As it goes up, it slows down, which means it is losing kinetic energy.
