The scenario that shows an object gaining potential energy and losing kinetic energy is the roller-coaster car slowing as it moves up a hill.
To understand why, we need to understand the concepts of potential energy and kinetic energy. Potential energy is the energy that an object possesses due to its position or state, while kinetic energy is the energy that an object possesses due to its motion.
When the roller-coaster car is moving up a hill and slowing down, it is losing kinetic energy because its motion is decreasing. At the same time, it is gaining potential energy because it is increasing its height above the ground.
So, in this scenario, the roller-coaster car is converting its kinetic energy into potential energy as it slows down and gains height.
