About gravitational potential energy

Gravitational potential energy is expressed as E = m g h.

Near Earth, g is about 9.8 m/s². Larger mass or height yields more energy.

Use kg, m and J for consistent SI results.

When objects fall, potential energy can convert into kinetic and heat.

g varies with location and planet, so adjust when needed.

This page provides quick mutual calculations for learning and estimates.

Quiz: gravitational potential energy

1. What is the basic formula?

E = m g h.

2. What is g near Earth?

About 9.8 m/s².

3. If mass doubles, what happens to energy?

It doubles.

4. If height doubles, what happens to energy?

It doubles.

5. What is the SI unit of energy?

Joule (J).

6. How to compute mass from energy and height?

m = E / (g h).

7. How to compute height from energy and mass?

h = E / (m g).

8. What does zero energy imply?

Mass or height is zero.

9. Why must units be consistent?

Mixed units produce incorrect results.

10. What can potential energy turn into?

Kinetic energy and heat.
