Newton's Third Law of Motion

 Back To Forces and Motion


"When object A exerts a force on object B, object B will exert an equal and opposite force back on object A."


Any time you touch an object, it is touching you with the same amount of force.





The forces here are equal and opposite. Neither the dog nor its owner pulls with greater force. They pull with the same force in opposite directions.


 Forces always come in equal and opposite pairs. This means that the forces are equal even when a big object crashes into a small object.

The forces will be equal when the truck crashes into the car.

Since the car is smaller, the car will have a greater acceleration.

How can anything move?
