Common questions
What is the Gravitational Potential Energy formula?
Gravitational Potential Energy is written PE = mgh. Energy stored due to position in gravitational field. It belongs to Mechanics, under Work & Energy.
What are the units in PE = mgh?
In SI units, PE is potential energy, measured in kg·m²/s²; m is mass, measured in kg; g is gravitational acceleration, measured in m/s²; h is height, measured in m.
How is the Gravitational Potential Energy formula derived?
Work against gravity: W = ∫mg dy = mgh. The result is PE = mgh.
