Newton's Second Law

Newton's Second Law can explain the motion of a brick. It can also explain the power in the boxers' punch. I can tell you from experience that the boxers' punch can be devastating!

Force is equal to mass x acceleration. This is Newton's Second Law according to Newton's laws of motion -Wikipedia, the free encyclopedia. If the mass of an object is increased, then its force is increased, if the acceleration of the object is increased, then its force is also increased.

Force, mass, and acceleration are all proportional. If you were to push (force) a brick with one hand, then the brick would accelerate. If you were to push the brick with 2 hands, then the brick would move with twice the acceleration. The reason the brick would move with twice the acceleration is because you're applying twice the force. If you were to push two bricks with one hand, then the bricks would move with half the acceleration. The bricks would move with half the acceleration, because you are doubling the mass and not changing the force. If you were to push three bricks with one hand, then the bricks would move with one third the acceleration. The bricks would move with one third the acceleration, because you are tripling the mass and not changing the force.

Why can a boxer hit so hard? He can hit hard due to accelerating his fist and body. He is trained to do this. So, if the boxer is more massive, then his punch will be harder. Remember, force is proportional to mass. But, he can also increase the impact of his blow by pivoting his body in such a way to gain sufficient acceleration. So, beware of fighting with a boxer. I used to amateur box, and I can tell you that a little man can exert a tremendous blow by using Newton's Second Law. He just increases the acceleration.

I was never a very bigger boxer at 160 pounds at 19 years old, but I could knock out 200 pound football player in the ring. I once stepped into the ring with a 200 pound football player who was untrained. I knocked him out in the first round. I also boxed a smaller 140 pound man who I felt hit harder than the 200 pound man. Somehow, the 140 pound man was able to gain substantial acceleration in his punch. I had never been hit so hard in my life. That is Newton's Second Law in action.

Beware the boxers' punch. According to Newton's Second Law, even a little man can exert a big punch. Force is equal to mass x acceleration. All the boxer has to do is increase his punches' acceleration. I have experienced this first hand. So take my word for it, be weary of messing with a boxer!
