Gravitational mass is determined by the strength of the gravitational force experienced by the body when in the gravitational field g. The Eötvös experiments therefore show that the ratio of gravitational and inertial mass is the same for different substances One Answer. 1. You are correct. The two forces are in opposite directions and cancel each other. Force is a vector quantity. When adding vectors the directions are as important as the magnitudes. Perhaps you are confusing gravitational field strength g = G M / r 2 and gravitational potential V = − G M / r. The former is gravitational force.

A massive object, like a star, will have a very large g-field. The Moon has less mass than the Earth, so its gravitational field is much weaker - approx 1/6 th of the Earth's. This means that we could jump higher on the Moon, and objects would fall more slowly, as they experience a weaker gravitational force
The gravitational field strength at its centre is zero, since attractive forces pull equally in all directions. Beyond the surface of the Earth, the gravitational force on an object decreases with increasing distance Where g = gravitational field strength, M = mass of planet (or object) and r = distance to the center of the planet (or object).
