Tennis ball but with a tennis bat go at 100 mph and probably a lot Father than you can throw a base ball. Wind resistance isn't the biggest issue
The two are the same, if you take the release of the ball and the landing of the punch as the same moment, Ie the conversion between kinetic energy and force.Not forget that kinetic energy is speed based not acceleration dependent
Your arm is really quite heavy half a pound weight added will make Only a very slight diffeance To how quickly you can reach max acceleration,, once you have reached max acceleration, which will happen early in the punching action the extra weight will add momentum making the PUNching arm movE quicker than if it was empty.
So yes marginally slower to reach max acceleration,But accelerated for longEr to a higher speed and Hold that speed better t
1. Now you're comparing throwing a baseball vs. being hit with a bat, which are two different things.
2. I don't see what the velocity of a ball being hit with a bat has to do with throwing a punch. If anything, it's an argument for using weapons, which is off topic in this discussion.
3. With the same amount of force, your maximum acceleration will be less with additional weight. It doesn't matter how much, the formula won't change. The overall punch will be slower with weights than it will without. You are correct there will probably be more kinetic energy, but kinetic energy is speed and other factors. It is the other factors, not the speed, which are increasing the kinetic energy in this case.
4. Why a half-pound weight? Two pounds was brought up as the "light" weight. I've done this exercise with 5-10 pound weights. I mean, sure, you can use a half-pound weight, but I don't really see the point then. As you said, it's not that much different from your arm.
