Action reaction forces never cancel each other out because

• They act on different objects.

• They act on the same objects

• They do not act on objects.

How is this an example of Newton’s Third law?

• Only the ball is using the head

• They are both exerting an equal force on each other

• Only the head is pushing the ball
