Newton's Third Law of Motion

Newton's Third Law Science

Newton's Third Law States: "For every action, there is an equal and opposite reaction."

In Newton’s Third Law of Motion there is always an action force and a reaction force. These two components always work together. The two forces will always the same amount of strength but they will act in opposite directions. An example of this is shown with this jet engine. The jet engine pushes forward and the flow pushes with an equal but opposite force backward. The action force in the picture below is the engine pushing left and the reaction force is the flow pushing right.

Although the same amount of force is applied to two objects they do not accelerate at the same speed. The object’s acceleration is dependent on the object’s mass. If a man fires a shotgun the bullet accelerates at a much faster rate than the gun in recoil. This is because the bullet’s mass is a lot less than the gun’s mass.
