Which of the following is an example of potential rather than kinetic energy?

a. water rushing over Niagara Falls

b. a molecule of glucose

c. a crawling beetle foraging for food

d. light flashes emitted by a firefly

A molecule of glucose

Explanation:

Kinetic energy is the energy possessed due to the motion of an object. Potential energy is the energy that is stored in the object. Out of given options, the example of potential energy is a molecule of glucose. When glucose breaks down, the energy is gets released in the form of ATP. Here, the glucose is static only is energy is getting stored in it.

Hence, the correct option is (b).
