The force of gravity is determined by the masses of the objects and their distance apart.
It's mainly to do with the mass of the planet, the more mass, the higher the gravitational pull of the planet. The two are related.
the density of the object that gravity is working upon determines it.
Gravity
The gravity on Mars or any other planet pulls you toward the planet's center.
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
gravity
Yes, gravity plays a significant role in preventing gases from escaping a planet's atmosphere. The strength of a planet's gravity determines the escape velocity required for gases to break free from the planet's gravitational pull. Planets with higher gravity, like Earth, are able to retain gases more effectively compared to those with weaker gravity.
Gravity is an attractive force that occurs between all objects with mass. The gravity of any planet will pull objects in.
No. The gravitational pull at the surface of a planet depends on that planet's mass and radius. Jupiter has the strongest gravity of any planet in the solar system: 2.53 times the surface gravity on Earth. Mercury has the weakest surface gravity at just 37% the gravity on Earth.
-- the masses of both objects that are being drawn together by gravity -- the distance between their centers of gravity
orbit the sun
No. The surface gravity of a planet is a product of its size and mass. It has nothing to do with distance from the sun. However, a planet farther away from the sun will experience a weaker pull from the sun's gravity.
