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? they will remain constant. they will both be recorded in joules. they will both be recorded in hertz. they will involve compressions.

You throw a ball upward and let it fall to the ground. your friend drops an identical ball straight down to the ground from the same height. is the change in kinetic energy (from just after the ball is released until just before it hits the ground) of your ball greater than, less than, or equal to the change in kinetic energy of your friend's ball?
