describe the motion involved in any given situation. Here's another chance to summarize what you've learned about each of Newton's three laws of motion. In this article we discuss how these laws are used. Newton's Third Law All forces result from the interaction of two bodies. When two bodies interact, they apply force on each other that are equal in magnitude and opposite in direction. Essentially it states that every force acting on an object also has a reaction force exerted by that . If a body A exerts a force on body B (an "action"), then body B exerts a force on body A (a "reaction"). = −7.20m/s2. Surely you've breathed, right? In simple terms this means: what went up must come down. What this means is that pushing on an object causes that object to push back against you, the exact same amount, but in the opposite direction. applications of Newton's Laws, but we first need to take care of the units of Newton's third law states that for every action there is an equal and opposite reaction. According to Newton's third law, the magnitude of the force that you exert on the rock is always exactly equal to the magnitude of the force of the force that the rock exerts on you. • Contact forces: an action-reaction pair of forces produced by two objects in physical contact • Forces are vectors • Newton's laws can be applied to each component of the forces independently Newton, N = kg (m/s2) = (kg ƒ m)/s2. • Newton's third law: If object 1 exerts a force F on object 2, then object 2 exerts a force -F on object 1.
