Problem

A ball is dropped from the top of a tower in the absence of air resistance. Which statement correctly describes how its kinetic and potential energies change as it falls? (a) Kinetic energy increases, but potential energy decreases by a greater amount.\text{Kinetic energy increases, but potential energy decreases by a greater amount.} (b) Both kinetic energy and potential energy remain constant.\text{Both kinetic energy and potential energy remain constant.} (c) Kinetic energy increases while potential energy decreases by the same amount.\text{Kinetic energy increases while potential energy decreases by the same amount.} (d) Kinetic energy remains constant while potential energy decreases.\text{Kinetic energy remains constant while potential energy decreases.}
