This document summarizes Newton's three laws of motion. Newton's first law describes inertia, the second law relates force, mass, and acceleration, and the third law details the action-reaction principle.

NEWTON I: A body will continue in its state of rest or uniform motion in a straight line unless acted on by a resultant force. This is called the “inertia” law. NEWTON II: The resultant force acting on a body is proportional to that body’s rate of change of momentum. In equation form F= m.∆v/∆t w...
NEWTON I: A body will continue in its state of rest or uniform motion in a straight line unless acted on by a resultant force. This is called the “inertia” law. NEWTON II: The resultant force acting on a body is proportional to that body’s rate of change of momentum. In equation form F= m.∆v/∆t which can be changed to F = m.a since ∆v/∆t = a NEWTON III: If body A exerts a force on body B, then body B exerts an equal but opposite force on body A. This is called “the action/reaction law” but do not use this as a definition. Important: If A exerts the force on B, THEN B MUST EXERT THE SAME SIZE FORCE ON A. It is not two forces acting on one body, but the same force acting on two different bodies.
