Newton's Third Law

Newtons third law states that:

“For every action there is an equal and opposite reaction.”


When you sit in your chair you push down with a force on it, but the chair pushes on you with an equal force in the opposite direction. As Newton says when two objects come in contact they exert forces upon each other.
