A student drops a feather and a bowling ball from equal heights in a vacuum. the objects land at the same time. which graph correctly shows the bowling balls total mechanical energy as it falls.
1 answer
A graph showing the total mechanical energy of the bowling ball as it falls would show a constant value of mechanical energy throughout the fall. The mechanical energy of an object in free fall (ignoring air resistance) remains constant because there are no external forces doing work on the object. Therefore, the correct graph would be a horizontal line representing a constant value.
