Would it be possible for someone to look over the parts of my lab report. If there is anything that I did not mention in the abstract, please inform me. I wasn't sure how I should end the paragraph. My teacher wants us to write our opinion on the success of the experiment (supported by results) but I am still confused about some of the questions. Specifically, I need help with calculating the percent of energy lost in the system.

The Attempt at a Solution
In a homework problem, I understood that kinetic energy is transferred to potential energy with rotational momentum conserved and that from that height can be derived. I don't know how to find that kinetic energy for the pendulum. I know that to find initial kinetic energy, I add the kinetic energy of both objects (1/2 mv^2) and to find final kinetic energy, I would use the final velocity of the mass (1/2(m1 + m2) * Vfinal = Kfinal. However, I don't believe that the same formula is used to find the potential energy for the experiment.
