What happens to the "lost" energy in these situations?
(a) A box sliding across the floor stops due to friction. How did friction take away that KE and what happened to that energy?
(b) A car stops when you apply the brakes. What happened to its kinetic energy?
(c) air resistance uses up some of the gravitational potential energy of a falling object. What type of energy did the lost PE become?
(d) When a returning space shuttle touches down on the runway, it has lost almost all its KE and gravitational PE. Where did all that energy go?
==========================
(a) I know the energy goes into the Earth but I'm not sure how friction takes away the KE
(b) The KE goes into the Earth ?
(c) does some of the PE get transferred as KE to the surrounding air?
(d) The earth?
correct me if I'm wrong
