Potential Energy Calculator

Find gravitational potential energy from mass and height.

Mass

Height

Gravity (m/s²)

Calculated Output

Potential energy (J) 490.5

Formula: PE = m × g × h

Step-by-Step Breakdown

1. Values used:

2. Mass = 5

3. Height = 10

4. Gravity = 9.81 m/s²

6. Potential energy = Mass x Height x Gravity = 5 x 10 x 9.81 = 490.5J

Did this calculator solve your problem today?

The math behind it

PE = mass × gravity × height. On Earth, g ≈ 9.81 m/s².

5 kg lifted 10 m → 5 × 9.81 × 10 = 490.5 J.

Where is the reference height?

You choose it (often the ground); PE depends on the height difference from that reference.
