Problem

A ball is dropped from a balcony. As it falls, which statement best describes the changes in its kinetic energy (K.E.) and potential energy (P.E.)? a) K.E. decreases while P.E. increases\text{K.E. decreases while P.E. increases} b) K.E. increases while P.E. decreases, and their difference remains constant\text{K.E. increases while P.E. decreases, and their difference remains constant} c) K.E. increases while P.E. decreases, and their sum remains constant\text{K.E. increases while P.E. decreases, and their sum remains constant} d) K.E. remains constant while P.E. decreases\text{K.E. remains constant while P.E. decreases}
