Mars' gravitational pull is 3.724 meters per second on the surface. The pull is 62 percent weaker than Earth's surface gravity which exerts a pull of 9.8 meters per second.
Gravity is calculated based on both a planet's mass and radius. A more massive planet will have a greater gravitational pull. However, a planet with a greater radius will have a smaller gravitational pull. This is due to the fact that gravity becomes weaker the further you are from a planet's core. Due to differences in gravity, a man weighing 200 pounds on Earth would only weigh 75.4 pounds on Mars.
