Newton’s laws of motion THEORY Isaac Newton formulated his three laws of motion in the 1600’s. These form the foundation for understanding motion in the everyday world. Two new concepts appear: force and mass . Definitions Force a push or a pull, measured in units called Newtons. Mass the amount of resistance to acceleration (inertia) a body offers Alternatively, mass is a measure of the amount of matter a body contains. Mass has units of kilograms. Here are the three laws of motion, I II Law of inertia: Law One I A particle moves in a straight line with constant speed if no net force acts on it. That is, Σ F = 0 v = constant.

Most famous equation in physics: Law Two If a net force acts on a particle of mass m then the particle accelerates, Σ F = F net = m a . Law of action-reaction: Law Three If particle two exerts a force on particle one, F 12 , then particle one exerts a force on particle two, F 21 . These forces are equal in magnitude but opposite in direction,
