Does having a roll of quarters in your fist actually ever help in a fight? Is it just a myth or is there a biomechanical advantage?
In: Physics
Mechanically it’s increasing the mass of your by about half a pound. Assuming you get a bit of a wind up and can get the hand to roughly the same speed as a normal punch (not likely to work for a 1″ punch) you’re going to be able to create more momentum, which translates into more force in the punch. If I had two bats… one ultra light (but didn’t give like a whiffle ball bat) or a heavier metal one… you’d probably want to get hit by the lighter one.
It also make your hand give a little less, so more force is imparted to the blow, but may do more damage to your fingers if they don’t have a place to move. That said, the goal is not to have a prolonged fight and you hope to deliver one knockout blow.
