  1. I’m extremely confused on the efficiency lab. We haven’t gone over energy, and I don’t know how to calculate it, what units to use, etc to determine the efficiency. I see in the syllabus we are going over energy tomorrow, seemingly too late to understand this lab and make a good grade… What is the energy?
    P.S. I’m assuming E = MC^2 isn’t going to be helpful?

    • Energy In = Energy before hitting the ground. Unless you throw the ball down, this is only from gravity.

      Energy Out = Energy after hitting the ground. This energy makes the ball bounce.
