Hello! Quick little background to my current question.. Whenever I would spar during boxing practice, I would always tire myself out from trying to "punch harder" (using all of my energy and trying to exert it on to my sparring partner). One day, a veteran boxer advises me on how I can perform better. He says "It's not about how hard you can hit, it's how fast you can hit. Speed creates power." I always wondered if this were true. I took it upon myself to answer if it were true or not with my basic physics knowledge from High School. I used Newtons 2nd law, F=MA. I assumed he was correct in a way because increasing the acceleration would create a higher force but that seemed too simple to answer since there are other variables. Would delivering a punch faster deliver a much greater force? Is this much more complex than I thought it would be? Is punching power even measured by force(newtons)? I'm pretty ignorant to things like this but I definitely appreciate any input.
