You all know Newton’s second law of motion that says that F = m * a (Force equals mass times acceleration). This makes sports interesting, for example boxing. A heavy boxer will always punch with more force than a lightweight boxer. This is due to his high mass. Even if the lightweight boxer has more punch acceleration, it is almost impossible to achieve two times more acceleration than the heavy fighter to compensate for the extra mass. I don’t want to discuss about the energy spent on this, which is also an important parameter because it shows how much time he can deliver such punches.
