Question

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? objects always have more potential energy than kinetic energy. kinetic energy increases and potential energy decreases when the velocity of an object increases. only potential energy decreases when an objects height increases. objects always have more kinetic energy than potential energy.

Explanation:

The roller - coaster example shows that as it descends (velocity increases), its potential energy decreases and kinetic energy increases. This aligns with the principle that kinetic energy ($K = \frac{1}{2}mv^{2}$) increases with velocity and potential energy ($U = mgh$) decreases as height ($h$) decreases.

Answer:

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