Surface Gravity

Gravitational acceleration at a body's surface.

Formula

g=GMr2g = \frac{GM}{r^2}

Variables

GGravitational constant
MMass
rRadius

Example

The Moon’s smaller mass and radius give it surface gravity of about 1.6 m/s².

Did You Know?

You would weigh nearly 2.5 times more standing on Jupiter's cloud tops than on Earth.
