We are learning about Emilie in physics right now and we are trying to determine if the equation for energy is e=mv or e=mv^2. Obviously we know the answer but I need to prove it using a block of clay a metal ball and a measuring device such as a ruler. I know how to do the experiment but I want to know if anyone knows where I can find information on the original experiment done by Emilie. I have tried google and I get one result if that. Any ideas or suggestions would be great.
