Here is the problem: Give the multiplicative constant for the kinetic, potential, thermal, and magic energy terms of the equation Total Energy (J)=E(kinetic)+E(potential)+E(thermal)+E… such that total energy has the units of Joules. Assume that KE=1/2mv^2, PE=mgh, TE= number, and magic energy= Obamacoefficient*pressure*volume. 1. KE: chains, slugs, jiffy, PE= chains, slugs, jiffy, TE: TNT equivalent, ME:jigger shotglass, PSI There are 3 questions. However, if you can help me do one. I'm not understanding the question.

    i thought all energy was magic energy

    Yup. Grad student professor is very political.

    \[KE=mv^2/2\]I suppose the kinetic energy coefficient is 1/2

    This is not even physics. Its more like useless unit conversion.

    because mv^2 already has the dimensions of energy

    so the coefficient for PE is the height

    think of the units

    I can't relate it to each other. Yes, they all have dimensions of energy. However, he wants you to find a coefficient so that if you're given the units in #1, you can just multiply them and get joules.
