Which detail in the section "Radiation Transfers Heat Through Space" BEST supports the conclusion that the amount of
potential energy in a ball at the top of a hill is the same as the amount of kinetic energy in the same ball at its fastest point?
In an energy transformation, energy changes form. A ball sitting on a hill has gravitational potential
energy, which is the ability for an object to do work due to its position in a gravitational field.
The higher on the hill this ball is, the more gravitational potential energy it has.
When a force pushes it down the hill, that potential energy transforms into kinetic energy. The ball loses
potential energy and gains kinetic energy.
On Earth, however, the ball's kinetic energy is transformed into heat by the opposing force of friction.
