- We know that the earth attracts all bodies towards itself due to the gravitational force or gravity.
- The force of attraction depends on the mass of the body.
- The more the mass, the greater the attraction between the body and the earth.
- The weight of a body is the force with which the earth attracts the body towards its center.
- It is the measure of gravitational pull on the body and hence it varies with the gravitational pull.
where,
W = weight of the object m = mass of the object
g = acceleration due to gravity(= 9.8 m s- 2)
