Potential Energy vs Mass
Formule
## Gravitational Potential Energy Potential energy represents stored energy due to an object's position in a gravitational field. ### Formula **PE = m * g * h** where m is mass, g is gravitational acceleration, and h is height above a reference point.
Exemple Résolu
A 10 kg object is raised 20 meters above the ground.
- 01PE = m * g * h
- 02PE = 10 * 9.81 * 20
- 03PE = 1962 J
- 04PE = 1.962 kJ
Questions Fréquentes
What is the reference point for height?
Height is measured relative to a chosen reference level, usually the ground. Potential energy is always relative to this baseline.
Does potential energy depend on the path taken?
No. Gravitational potential energy depends only on the vertical height difference, not the path. Gravity is a conservative force.
What happens to PE when an object falls?
As an object falls, PE converts to kinetic energy. At ground level, all PE has been transformed into KE (ignoring air resistance).
