NEWTON'S LAW OF MOTION DEFINITIONS Every object in a state of uniform motion tends to remain in that state of Newton’s First Law of Motion: motion unless an external force is applied to it. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. Newton’s Second Law of Motion: The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors in this law the direction of the force vector are the same as the direction of the acceleration vector. DEFINITIONS Newton’s Third Law of Motion: For every action there is an equal and opposite reaction. For every action there is an equal and opposite reaction. NEWTON’S FIRST LAW OF MOTIONS ACTIVITIES 1. Grab a ball and throw it and let hit the ground or let someone catch it , this will explain newton’s 1st law 2. Get a toy car and push it forward and let someone try to catch it. It will stop on its own because friction is always acting on it. NEWTON’S FIRST LAW OF MOTIONS ACTIVITIES 1. for this activity you must grab a chair and push it, the force you apply is the direction of the chairs acceleration 2. You must get a nerf gun, a nerf gun demonstrates this because it pushes air into the nerf bullet and gives it acceleration. NEWTON’S THIRD LAW OF MOTION ACTIVITIES 1. get on top a skateboard and try to move your body forward and the skate board will go backward (and leave you on the floor if not careful) 2. if you were to get on a boat and it was heading toward shore if you jumped off you would push the boat back (and leave your face on the sand if not careful)
