Net Force | When the total amount of force applied to an object equal zero. |
Newton | A measurement of force. |
Newton's first law | An object in motion will stay in motion, and an object at rest will at rest unless acted upon by an unbalanced force. |
Newton's second law | Force is equivalent to mass multiplied by acceleration, and similarly, Acceleration is equivalent to force divided by mass. |
Newton's third law | Every action produces an equal but opposite reaction. |
