Gravitational force equation Calculator

Newton's Law of Gravity states that 'Every particle attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the distance between them.

where,

G = Universal Gravitational Constant = 6.6726 x 10-11N-m2/kg2 m1 = Mass of Object 1 m2 = Mass of Object 2 r = Distance Between the Objects.

Case 1:

Determine the force of gravitational attraction between the earth 5.98 x 1024 kg and a 70 kg boy who is standing at sea level, a distance of 6.38 x 106 m from earth's center. m1 = 5.98 x 1024 kg, m1 = 70 kg, r = 6.38 x 106 m, G = 6.6726 x 10-11N-m2/kg2

Substitute the values in the below Gravitational Force formula:

This example will guide you to calculate the Gravitational Force manually.

Case 2:

Find the mass of one object if the magnitude of the gravitational force acting on each particle is 2 x 10-8, the one mass is 25 kg and the objects are 1.2 meters apart F = 2 x 10-8, m2 = 25 kg, r = 1.2 m, G = 6.6726 x 10-11N-m2/kg2.
