Which statement best compares potential and kinetic energy? a. objects always have more potential energy than kinetic energy. b. only kinetic energy increases when the velocity of an object increases. c. only potential energy decreases when an object’s height increases. d. objects always have more kinetic energy than potential energy.

B. Only kinetic energy increases when the velocity of an object increases.  

Explanation:

As we know that kinetic energy is given by the formula

so kinetic energy directly depends upon the speed of the object

Also we know that gravitational potential energy depends on the height of the object

so it is given as

so here on increasing height the gravitational potential energy will increase

so here correct answer must be

B. Only kinetic energy increases when the velocity of an object increases.
