since the weights will be falling, it has KE, and we know that at the top, before the fall, PE=KE, meaning, milliseconds before the weight hits the cube, all the PE is now KE. This allows me to find its velocity right before impact. Since i now have its velocity, i can find KE on impact. All the KE will be transferred into the cube. A transfer of energy is work done

ok, so we all know that work done = force(distance) so force =work done/distance.

Here is my issue, i don't know distance. Usually distance is some sort of deformation or if the weight falls on a nail, its the distance the nail is driven into the wood. So i am not sure what to use as my distance?? should i use a value close to 0, but not 0??

i do not have access to a izod or charpy tester, nor do i have the time to make one.

i want to try it out this way and see what happens. Ill plot the data in excel and see what i can find:)

thanks
