Newton's Three Laws:
Law 1.) An object at rest stays at rest, an object in motion stays in motion unless acted upon by an equal or opposite force. In simpler terms An object that isn't moving cant move. An object that is moving keeps moving unless a force equal or bigger is forced upon. Law 2.) F=MA. This law is an equation which is Force = Mass x Acceleration. So this equation will help us find either force, mass or the acceleration for an equation. For example: . A force of 20 N acts upon a 5 kg block. Calculate the acceleration of the object. You would do the formula A=F/M because if you need to find the answer to a unit that isn't F you would divide. Law 3.) For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. My Newton's second law video is at 1:15 : |
