The Third Law:For every action, there is an equal but opposite reaction.
Meaning that whenever a force is exerted on a body, the body exerts a reaction force back. The size of the reaction force is same BUT it is directed in the opposite direction, meaning that forces always occur in pairs. Newton's Third Law can also be referred to as the Action-Reaction Law. |
Newton's Third Law of Motion and Bronte Campbell/ Olympic Swimming |
In Olympic Swimming, Newton's third law of motion can be applied to the freestyle stroke. When an athlete's hand travels downward into the water so that the swimmer can be propelled forwards, an equal and opposite reaction is formed as the swimmer moves through the water. The force of the swimmer's hand through the water is met with the force of the water pulling against it, so that the athlete moves.
