Newton's Law

Newton’s 1st law of motion: If no external force is acting on it, an object will, if stationary, remain stationary, and if moving, keep moving at a steady speed in the same straight line Newton’s 2nd law of motion: F = m × a -acceleration is proportional to the force, and inversely proportional to mass Newtons 3rd law of motion: if object A exerts a force on object B, then object B will exert an equal but opposite force on object A or, more simply: To every action there is an equal but opposite reaction
