Why aren't the potential and kinetic energy readings that we compare exactly
the same?
Pretend you were sliding down a snow hill on a sled with no friction,
just like the cart in the experiment. During your descent of the hill describe
how your gravitational potential energy, kinetic energy, and total energy
change.
