Gravity Pull on Mars

Gravity Pull on Mars

If you were on Mars, it would pull you down with a force about two fifths as strong as the force of Earth's gravity. You could lift objects that weigh almost three times as much compared to similar objects here on the Earth. You could jump up almost three times higher, and it would take much longer to fall to the ground from the same height.
Even though it looks as though you would be like a comic-book hero on Mars, you would still have to worry about the mass of an object. A large object that is moving forward would still crush you if you got in its way, just like it would be a problem here on the Earth, and a bullet from a gun would do just as much damage on Mars as it does on the Earth. A vehicle that travels on the surface of Mars would have the same problems trying to stop as it would on the Earth, but an interesting problem would be that because of the reduced gravity a vehicle would not "grip" the ground on Mars as strongly, making it harder to stop if you are traveling at a high speed.

Who was it named after?
In Roman mythology, Mars was the god of war and agriculture. The planet Mars was named this because Mars is red like blood.
