Is total energy (T.E) conserved in every case (within experimental error)? Yes or No [If not, where did the missing energy go?]					What if the mass of the ball changed from 0.01 kg to 1.0 kg? Is total energy (T.E.) conserved in every case (within experimental error)? Yes or No [If not, where did the missing energy go?]					What if the air resistance on the ball changed from 0.0 to 0.05 kg/m*s (change the mass back to the original value, 0.01 kg and go the "World" menu?) Is total energy (T.E.) conserved in every case (within experimental error)? Yes or No [If not, where did the missing energy go?]
