This is a picture of Newton's 3rd Law. The object on the table is pushing down on the table. The table is pushing back up on the object. There is equilibrium and a action reaction force.

Newton's third law states that when one object exerts a force on another object that object exerts an equal and opposite force as the first one did. The object that is exerting the force feels a reaction force from the other object. The interaction between the two objects is a mutual action where each object exerts an equal but opposite force. The action force is the forces of the pair of objects. The reaction force is the force that is equal in strength and opposite to the action force which acts simultaneously on the object that is exerting the action force. A force is always apart of another equal and opposite force.

 

The foot is pushing backward off on the skate board and the skate board is pushing forward on the foot.

This picture is a action reaction picture of me. I am pushing on the wall and the wall is pushing back on me with an equal but opposite force.

 Newton's third law is used everyday and there are many examples of it. When you push against a wall the wall pushes back on you. You are the action force and the wall exerts the reaction force. When you are walking your shoes apply force to the ground and the ground pushes back up on you with an equal and opposite force. However, another example is when a bird is flying and it uses its wings to push the air downward and the air pushes back up on the bird. Another example is when you place a book on a desk. The book is attracted to the earth because of gravity pulling on it and the desk is applying a reaction force by pushing back up on the book.
         

This is an image of cars crashing and this resembles a action reaction force because the red car crashes against the green car and the green car pushes back on the red one.
