lets consider a scenario of a roller - coaster ride. as the roller coaster at the top begins to descend, it loses height, which means its potential energy decreases and kinetic energy starts increasing and reaches its maximum value. by using the above scenario, which statement best compares potential and kinetic energy?\nobjects always have more potential energy than kinetic energy.\nkinetic energy increases and potential energy decreases when the velocity of an object increases.\nonly potential energy decreases when an objects height increases.\nobjects always have more kinetic energy than potential energy.

Answer

Brief Explanations:

In the roller - coaster scenario, as it descends, height decreases (so potential energy $U = mgh$ decreases) and velocity increases (so kinetic energy $K=\frac{1}{2}mv^{2}$ increases). Potential energy is related to height and kinetic energy to velocity.

Answer:

Kinetic energy increases and potential energy decreases when the velocity of an object increases.
