# Gravitational field strength formula - Gravitational field strength formula and definition    KEY POINT - The relationship between gravitational field strength and potential gradient is: where ΔV is the change in potential over a small distance Δx. The strength of a gravitational field is a function of the mass of an object. ### Gravitational Field: Definition & Formula ### The Formula For Gravitational Field Strength  Radiant energy such as light has mass and so is affected by gravitational fields.  Every mass placed in its surrounding must experience the gravitational force toward the centre of the shell.  Sexy:

Geologists and prospectors of oil and minerals make precise measurements of the earth's gravitational field to predict what may be beneath the surface. This article will go over the strength of gravitational fields and provide an example of how to calculate them.

g (r) = Earth’s gravitational field strength, G = gravitational constant () = mass of the Earth r = distance from the center of the Earth (m). The gravitational pull between two objects only affects their motion when at least one of the objects is very massive. Earth has a mass of about 6 × 1024 kg.

The gravitational force experienced by the mass, m is given by F = G Mm/r^2 So the field strength at this point in space, g = Gravitational force per unit mass = F/m So, g = G M/r^2. This is the formula of Gravitational field strength. Also Read: Law of Gravitation & derivation of the formula for Gravitational force
