Although all energy is kinetic and potential* it is convenient to break it up into coherent macroscopic kinetic energy (KE), macroscopic potential energy (PE), thermal energy (ThE = kinetic and potential energy of molecules due to random motion), chemical energy (ChE = kinetic and potential energy of electrons in atoms in molecule). Consider a small rocket placed on a pad containing an electrical igniter. The rocket is attached to a small packet of chemical explosive in its tail. The igniter lights a short fuse that ignites the chemical explosive shooting the rocket upward. It rises straight up about 50 feet, then falls to the ground where it bounces and comes to a stop.Consider three times: t0 = just after the explosion has completed but the rocket has not risen much t1 = the rocket is just at the top t2 = the rocket has fallen to the ground and come to a stop Identify what has happened to the various energies of the rocket (not including the explosive packet or fuse) from the beginning to the end of the time segments indicated. Choose "positive, negative, zero, or cannot be determined from the information given" in each of the following questions to indicate whether the rocket's energy had increased, decreased, or remained the same. Then explain how you decided each of the changes.* Of course this does not conclude the energy contained in mass (E = mc2) that we have to include when we get to the physics of the atomic nucleus!  Part (a) Between t0 and t1, what was the change in the rocket's kinetic energy?  Part (b)  Between t0 and t1, what was the change in the rocket's potential energy?  Part (c)  Between t0 and t1, what was the change in the rocket's thermal energy?  Part (d)  Between t0 and t1, what was the change in the rocket's chemical energy?  Part (e)  Between t1 and t2, what was the change in the rocket's kinetic energy?  Part (f)  Between t1 and t2, what was the change in the rocket's potential energy?  Part (g)  Between t1 and t2, what was the change in the rocket's thermal energy?  Part (h)  Between t1 and t2, what was the change in the rocket's chemical energy?
