Chapter4Friction Newton’s 1 st Law~ an object moves with a V that is constant in magnitude and direction unless acted on by a non-zero force. 2 nd ~ The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass 3 rd ~ If object 1 & 2 interact, the force F12 exerted by object 1 and 2 is = in magnitude but opposite in direction to the force F21 exerted by obj 2 on 1.
