Newton’s Laws of Motion

One of the most marvelous discoveries in science ever made is the three laws of motion. An object remains in a state of motion until an external force is applied to it. The second is force equals mass times acceleration. The third and most well known is for every action there is an equal or opposite reaction. These three laws are responsible for changing our understanding of physics and the universe.
