Force and Motion
... friction – resistance to motion that occurs whenever two materials, or media, are in contact with each other. • air resistance is a form of friction • Sometimes we want to increase friction. (ex: cinder an icy road) • Other times we want to reduce friction. (ex: change your oil) • For ordinary solid ...

Newton`s Laws and His System of the World
... But no matter what the origin or cause of the force, and no matter where in the universe it happens, its effect is always given by the same equation, Fnet = ma. Newton's second law is so powerful precisely because it is so general, and because we can apply it even though at this stage we may be comp ...
