On Mars, you weigh 37.7% as much as you would on Earth. If you weigh 100 pounds on Earth, you weigh only 37.7 pounds on Mars. If you weigh 150 pounds on Earth, you weigh only 56.6 pounds. The equation is .37 x Earth weight = Martian weight.

The force of gravity varies depending on the masses and distance between both objects. The mass and radius of Earth as compared to Mars is different. Therefore the force of gravity is stronger on Earth.

For starters, only your weight changes. That is because weight is the gravitational pull on an object. Earth and Mars do not have the same gravity level, therefore your weight changes. But your mass does not change because mass is all the matter in your body, and that remains the same.

Mars has weaker gravity than Earth does due to its lower mass, so you weigh less on Mars.

The mass of Mars is much less than the mass of Earth, and the distance from the Martian surface to the center of Mars is about half the distance from Earth's surface to Earth's center.

Because there is less gravity on Mars.
