Newton's
third law states that "Every action has an opposite and equal
reaction". This means that there is always a pair of force acting on
both interacting objects. In the video, as Karlee hits the ball, she
uses a force upon the ball and makes it move. However, according to
Newton's third law, the ball also reacts on Karlee racket's with the
same amount of force. Thanks to the tennis racket vibration dampener,
which role is to reduce or eliminate the vibration coming from the
reaction of the ball so that we don't have much impact from that
reaction. Another example from our world is when a person punches the
wall. The stronger he punches, the more strength the ball will reaction
on his knuckles and fist. As a result, it cause injuries.
