Newton’s Third Law Of Motion

 

Newton’s Third Law Of Motion

Statement: To every action, there is an equal and opposite reaction.

It means that if a body A exerts a force F1 on a body B, and the body B exerts a force F2 on body A, then:

F1=F2

That is, they are equal in magnitude but opposite in direction.

Whenever two bodies interact, they will exert equal and opposite forces.

This law can be observed anywhere and everywhere in the surroundings. Some examples of action-reaction pairs are mentioned below:

1) A swimmer pushes the water backwards by their hands, and in return, the water pushes the swimmer forwards, thus enabling him to go forward during swimming.

2) A man walking on the ground: While walking, a person pushes the ground in the backward direction, and the ground in return pushes the person in the forward direction, thus making them walk.

3) A bird while flying pushes the air downwards with the help of its wings. Consistent with Newton’s third law of motion, the air makes the bird upwards.
