Sir Isaac Newton created three scientific laws. They are known as
Newton's Laws of Motion. The first law describes what inertia is and
the second law describes how the mass of an object ant the force
exerted on an object are related to the objects acceleration. This
website was created for a high school physics project and focuses on
Newton’s Third Law of Motion. Newton’s Third Law tells about
action/reaction pairs; for every action there is an equal but opposite
reaction. This site should tell you the science behind the Third Law.
