How Do You Calculate Gravity Of A Planet
This force of gravity depends on a few things. The Relationship Between Gravity and Mass and Distance As stated above your weight is a measure of the pull of gravity between you and the body you are standing on.

When you stand on a scale what its actually doing is measuring how hard Earths gravity is pulling on you.
How do you calculate gravity of a planet. Thats because the planets weigh different amounts and therefore the force of gravity is different from planet to planet. If you double your mass gravity pulls on you twice as. First it depends on your mass and the mass of the planet you are standing on.
In this equation G is Newtons gravitational constant M is the mass of the planet youre escaping from in kilograms and r is the radius of the planet in meters. Calculate the acceleration due to gravity on the surface of the Earth. If you were to step onto a scale on another planet it would say something different than it does here.
Cavendish set up an experiment with two 150 kg lead balls planets and two smaller spheres moons. To calculate escape velocity multiply 2 times G times M then divide that by r and take the square root of the result. Through his findings scientists now calculate a planets weight by the time it takes for objects to orbit the planet and the distance of those objects from the planet.
The mass of the Earth is 5979 1024 kg and the average radius.
