What is surface gravity?

Surface gravity = GM/R². Earth = 9.807 m/s². Moon = 1.62 m/s² (16.5% of Earth). Mars = 3.72 m/s² (38% of Earth). Jupiter = 24.79 m/s² (252% of Earth). Your mass stays the same — your weight (force of gravity) changes. Weight = mass × gravitational acceleration.

Why is gravity different on each planet?

Gravity depends on planet's mass and radius: g = GM/r². Jupiter has much more mass than Earth (318×), so stronger gravity despite being larger. Mars is smaller and less dense than Earth → lower gravity. The Moon has 1/81 Earth's mass but only 1/4 the radius → 1/6 gravity.
