Newton’s Third Law of Motion states, “When one object exerts a force on a second object, the second one exerts a force on the first that is equal in magnitude and opposite in direction.”
This law is sometimes called the “Law of Action and Reaction”.
A swimmer swimming forward:
:The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward.
A ball is thrown against a wall:
:The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
A person is diving off a raft:
:The person puts a force on the raft (action force) pushing it, and the raft puts a force on the diver (reaction force) pushing them in the opposite direction.
A person pushes against a wall
:(action force)and the wall exerts an equal and opposite force against the person (reaction force).
The Space Shuttle engines push out hot gases :(action force), and the hot gases put a force on the shuttle engines (reaction force) so the shuttle lifts (there is no sling shot doing it!)
