Question

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

Explanation:

Potential energy (for gravitational - near Earth's surface $U = mgh$) increases with height. Kinetic energy ($K=\frac{1}{2}mv^{2}$) increases with velocity. In a conservative - system (no non - conservative forces like friction), when kinetic energy increases, potential energy decreases and vice - versa to conserve total mechanical energy ($E = K + U$).

Answer:

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