gabriel is performing an experiment in which he is measuring the energy and work being done by a ball rolling down a hill. which statement best describes gabriel’s measurements?
a. they will remain constant.
b. they will both be recorded in joules.
c. they will both be recorded in hertz.
d. they will involve compressions.

The statement that best describes Gabriel's measurements are that B. They will both be recorded in joules. There is a change in energy as the ball starts to roll from the hill and when it is rolling quite fast, thus it has a greater kinetic energy, because of this change in energy from potential as it is on top of the hill to when moving down the hill, kinetic, there is a change in energy and thus work on the object, the ball.

The solution is that since work, indicating a change in energy and energy itself is measures in joules, the answer should be B.

Is there a picture or answer choices?
