Newton's 3rd law of motion states that when 2 bodies interact with each other, they will exert an EQUAL and OPPOSITE force of the SAME type on each other. This proves the conservation of momentum theory where no momentum can be created or destroyed.

For every action, there is an equal and opposite reaction

Newton's 3rd Law of Motion is very simple: "For every action, there is an equal and opposite reaction."

This means that whenever one object pushes or pulls on another object, the second object pushes or pulls back with the same amount of force but in the opposite direction. For example, if you push against a wall, the wall pushes back against you with the same force, even though the wall doesn’t move.

It’s like when you jump off a boat: you push down on the boat with your feet (action), and the boat pushes you upwards (reaction). Fascinating question: Ever wondered how you move forward when you walk?

Does this make sense, or is there anything you’d like me to explain further?

Action and Reaction are equal and opposite or to every action, there is equal and opposite reaction.

The third law states that for every action in nature there is an equal and opposite force.

Every force has an equal and opposite reaction force. Keep in mind they act on different objects. Both the forces are the same type (contact or non contact) and have the same size and opposite direction.

If body A applies a force on body B, then body B will apply an equal and opposite force on body A

Hi Reginold the third newton law is : For every action there is a equal opposite reaction, :) hope that helps

For every action, there is a reaction equal and in the opposite direction. Or in detailed response: If object A exerts a force on object B, object B will exert the same force in the opposite direction to object A.

Newton's 3rd Law states that when two bodies interact, they exert forces on each other that have the same magnitude but the opposite direction

Whenever two objects interact, the forces they exert on each other are equal and opposite. So for every action there is an equal and opposite reaction!

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction. In simpler terms, this means that if you push on something, it pushes back on you with the same amount of force. For example, if you press your hand against a wall, the wall pushes back against your hand with an equal force.

Newton's 3rd Law is associated with the saying 'for every action there is an equal and opposite reaction'. It essentially states that forces can never exist in isolation - they always come in 'action-reaction pairs'.


Right now, you are most likely sat on a chair - and you can feel your weight (a force) pushing down on the chair. At the same time, the chair is exerting a force (called the normal force) on you! This is an example of Newton's 3rd Law: you are pushing on the chair, and the chair is pushing on you. This law can explain everything from cars driving on the road, to people paddling their canoes in a river and to rockets blasting off into space!


If in doubt, hopefully this can help you to remember too:
