Newton`s Three Laws of Motion
... • An object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an unbalanced force. • Unbalanced forces cause acceleration. – When you roll a ball, why doesn’t it roll on forever? FRICTION – This concept is also referred to as the Law of Inertia ...
