The cart loses kinetic energy (KE) and gains potential energy (KE) as it slows down while traveling to the top of the roller coaster.
Kinetic energy can be defined as a form of energy that is possessed by a person due to its motion or change in velocity (acceleration).
Potential energy refers to a form of energy possessed by a person due to its height (position) above planet Earth.
In this scenario, as the cart travels from the bottom of the roller coaster to the top, kinetic energy (KE) is lost but converted into potential energy (PE) and its PE is greatest at the top of the roller coaster.
In conclusion, cart loses kinetic energy (KE) and gains potential energy (KE) as it slows down while traveling to the top of the roller coaster.
