Frequently Asked Questions
What is the formula for surface gravity?
g = G·M / r², where G = 6.674e-11 N·m²/kg², M is the body's mass, and r its radius.
What is Earth's gravity?
About 9.81 m/s² at sea level. It varies slightly with latitude (poles vs equator) and altitude.
How much gravity is on Mars or the Moon?
Mars: ~3.71 m/s² (0.38 g). Moon: ~1.62 m/s² (0.17 g). Both lighter because of smaller mass.
