If the mass of an object is held constant, increasing force will increase acceleration. If the force on an object remains constant, increasing mass will decrease acceleration” (How Newton’s Laws of Motion Work). Newton equated forces so that he could differentiate the change in momentum per unit time. Momentum is a characteristic involving a moving body using the product of the body’s mass and velocity. To determine the differential change, Newton created differential calculus and created an original equation. That equation …show more content…
This means that any action force has a reaction force equal in magnitude. An example of this would be someone punching a wall. Punching the wall is an action force, but the reaction force is when we feel the pain. If we punch the wall too hard, we can possibly break a bone or just bruise the bone depending on how much force we use on the wall. When gravity keeps you on the ground, the ground will push against your feet. When one object is much bigger than another, the acceleration is imparted to the second object, and the acceleration of the first object is ignored. For example, when you throw a baseball, you don 't have to consider that you caused a rotation of the earth to speed up while the ball is in the air. When a baseball bat strikes a ball, the bat applies a force to the ball and accelerates rapidly after getting struck by the bat, but the ball has to apply a force to the bat. The mass of the ball is compared to the mass of the bat including the batter. With a wooden baseball bat, you can see the amount of force evident as the ball strikes the bat and the bat breaks into
