Earth pulls down on you with a gravitational force that you call your weight. Do you pull up on Earth with the same amount of force?
Solution Step 1 of 2 Yes, According to newton’s third law, for every action there is a reaction force which is equal in magnitude but opposite in direction. Here when we stand on the earth surface; since both the earth has mass M and a person has mass m. As they have masses,they are acted by an attraction force between them called gravitational force; which is directly proportional to the product of masses and inversely proportional to square of the distance(r). GMm That is FG= r2 Where G is universal gravitational constant. Fep = F pe= F G Where F epis the force of earth on person called weight,peis the force of person on earth and F Gs gravitational force.
