Which of the following is an example of gravitational potential energy?
A
A car moving at a constant speed
B
A compressed spring
C
A battery powering a flashlight
D

Understand the concept of gravitational potential energy: It is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.
Identify the key characteristic of gravitational potential energy: It depends on the object's mass, the height above the reference point, and the gravitational acceleration.
Analyze the options given: A car moving at constant speed has kinetic energy, a compressed spring has elastic potential energy, and a battery powering a flashlight involves chemical energy.
Consider the correct answer: A book placed on a shelf has gravitational potential energy because it is elevated above the ground, and its energy is due to its position in the gravitational field.
Conclude that gravitational potential energy is associated with objects that have height in a gravitational field, such as the book on the shelf.
