Independent research - paintball

independent research - hockey

Homework Statement

I have been assigned a physics project to do over the break. I need to research the design and use of a piece of protective equipment - I have decided on hockey equipment.

2. The attempt at a solution

The most obvious feature is that the equipment creates a larger distance over which the object can decelerate before hitting the body. I have read on some companies' websites that the equipment actually redirects impact away from sensitive areas (knees, shins, etc.). I appreciate any suggestions of other safety design features I can focus on.I was also thinking of doing the assignment on paintball - specifically how the mask is used to keep players safe. I'm having trouble deciding which one would include more applications of physics.

i guess for paintballing you can say the mask increases time which decreases the force
a car would be better i think

Do what the guy above says. If you do something on paintball gaurds your report is going to be as boring as hell. However if you did something on cars, or my choice which would be kevlar bullet proof vests (I know its not very original) you would have loads of physics to talk about and what's more you would be able to apply it to real like situations which would make your report/presentation stand out a lot more.

I think basically there are two sorts of protection: that which reduces the velocity before impact using friction (e.g. the crash zone of a car) and that which spreads out the force of the impact over a large area instead (e.g. bullet proof vest).
