Newton`s Laws - Ipod Physics
... Third Law If two objects interact, the force exerted on object 1 by object 2 is equal in magnitude but opposite in direction to the force exerted on object 2 by object 1. The classic way of saying this is, “For every action there is an equal and opposite reaction”. Newton’s third law simply says t ...

Newton`s Law of Motion
... • Air resistance acts in the opposite direction to the motion of an object through air. • If the object is falling downward, air resistance acts upward on the object. • The size of the air resistance force also depends on the size and shape of an object. ...

... Newton's laws of motion describe the motion of objects acted on by forces, doing so to a very good approximation as long as the speeds are small compared with the speed of light. Newton's first law of motion states that an object remains at rest or moves with constant velocity unless acted on by a r ...
