POSSIBLE POINTS: 1 After the Frisbee falls to the ground, you throw one of them back up into the tree, where it comes to rest on a branch.

Compared to when the Frisbee was on the ground, which of the following is true about the potential energy of the system?

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

If 130 j of energy were added to 1 kg of each of the samples listed in the answer choices, which would experience the greatest temperature increase

Are good conductors of heat also good conductors of electricity? explain your answer.
