This also means that the harder you kick a ball the farther it will go. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. If the same force is applied to two objects of differ- ent mass, the heavier object has less acceleration than the lighter object (Figure 1). Newton's 3rd law of motion states that action and reaction are always equal but opposite in direction. In simple terms, it means that a larger force will change the momentum of an object more quickly as compared to a smaller force. Newtons laws first appeared in his masterpiece, Philosophiae Naturalis Principia Mathematica (1687), commonly known as the Principia. When you jump, your feet apply force to the ground, and the earth applies an equal and opposite reaction force that pushes you into the air. Force exerted by an object equals mass times acceleration of that object: F = m * a .
