## Gravitational Force Equation / Formula

Gravitational Force :
F = Gm1m2 r2

Mass of Object 1 :
m1 = Fr2 Gm1

Mass of Object 2 :
m2 = Fr2 Gm1

Distance between the Objects :

$r = \sqrt{\cfrac{G \space m_1m_2}{F}}$
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.

Gravitational Force Calculator helps to find force of gravity using Newton’s Law of gravity. Newton’s Law of Gravity states that two particles attract each other with forces. This principle is directly proportional to the product of their masses which is divided by the square of the distance between the particles. In short, when two bodies attract each other with equal and opposite forces it is said to be Newton’s Law of gravity. Newton’s Law of Gravity is denoted by the symbol “F”. The SI unit of Newton’s Law of Gravity is Newton Meter (N).

## The force of gravity calculator

Newton’s Law of Gravity states that every point mass attracts every single other point mass by a force pointing along the line interesting both points. This advanced online Newton’s Law of Gravity Calculator is used to calculate and find the gravitational force between two objects when mass and distance between the objects are known.

Example:
Calculate the Newton’s Law Gravity for the given details of objects.
Mass of Object 1(m1) = 5 kg
Mass of Object 2(m2) = 10 kg
Distance between the objects (r) = 15 m

Solution:
Apply Formula:
F = Gm1m2 r2
F = 6.6726 x 10-11N-m2/kg2 *5*10/152
F = 1.48E -11 N
Gravitational Force (F) = 1.48E -11 N

what is the magnitude of the gravitational force between two 1-kg bodies that are 1 m apart?
Applying Formula:
F = Gm1m2 r2
6.67 x 10^-11
Magnitude of the gravitational force = 0.0000000000667 N
