## Gravitational force and its properties

Gravitational force is the weakest force in nature. There are many properties of gravitational force, but first of all let us discuss about the various fundamental forces present in nature. There are mainly four types of forces exist in nature:
1. Gravitational force
2. Weak nuclear force
3. Electromagnetic force
4. Strong nuclear force.
Today I will discuss about the gravitational force
We all know that earth and other planets revolve around the sun but why? We are attracted towards the earth due to gravity of earth or in simple words force of attraction of earth. Basically gravitational force is the force between any two objects. The objects can be microscopic or macroscopic. Continue reading “Gravitational force and its properties”
