Chapter4Friction
Newton’s 1
st
Law~ an object moves with a V that is constant in magnitude and direction unless acted on by a nonzero 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. Gravitational Force
