PRESENTATION OUTLINE
Newton's third law of motion states that "for every action, there is an equal and opposite reaction." This means that if a person pushes the wall, the wall will push back on the person. An action force is the force that is applied to an object, and a reaction force is the force that occurs in response to the action. Action/reaction pairs are similar to cause and effect scenarios. For every action, there is an equal and opposite reaction.
In this example, we can see that the pencil case is sitting on the desk. It is exerting a force onto the table, and in return, the table is exerting an equal and opposite reaction onto the pencil case.
In this example, it appears that the person is holding a crayon in their hand. They exert force onto the crayon, and the crayon reacts by exerting an equal and opposite reaction. To go in depth with this example, one could also say that the crayon is pushing onto the paper (action) and that the paper is pushing back onto the crayon (reaction).
Finally, this example shows a gymnast preparing to launch off of a "horse". His hands are applying force to the metal handle, and the metal handle is reacting by applying force onto the mans hands.
"FOR EVERY ACTION, THERE IS AN EQUAL AND OPPOSITE REACTION"
