Newton's three laws of motion are presented: 1) Law of inertia - an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force 2) F=ma - force equals mass times acceleration 3) Action-reaction - for every action there is an equal and opposite reaction The document provides explanations and examples of each law, including friction forces, the definition of a newton, and how action-reaction forces apply to interactions between objects.
