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.
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 know the basics of potential and kinetic energy. Potential energy refers to the stored energy an object has due to its position or condition, while kinetic energy refers to the energy of motion.
In the first scenario, the roller-coaster car is accelerating as it moves down a hill, which means its speed is increasing. Since kinetic energy is directly related to an object's speed, the car gains kinetic energy in this scenario.
In the second scenario, the roller-coaster car is slowing as it moves up a hill. As the car moves against the force of gravity to climb the hill, its speed decreases, and thus its kinetic energy decreases. At the same time, the car is gaining potential energy due to its increased height above the ground.
Therefore, the second scenario, roller-coaster car slowing as it moves up a hill, shows an object gaining potential energy and losing kinetic energy.
