Question

Gravitational potential energy is directly proportional to .

• A. height
• B. temperature
• C. speed

Answer 1

The correct option is A height

Potential energy, $P.E=mgh$
where, $m$ is the body's mass, $g$ is the acceleration due to earth's gravity and $h$ is the body's height from the ground.
From the above equation, it is clear that, potential energy of a body is directly proportional to the its height ($m$ and $g$ are constants for a given body) from the ground. The higher the body is from the ground, the greater will be its potential energy.
