CRB True or false? All changes in potential energy are equal to the opposite of work done by gravity (PE = - Wgrav). False. Changes in potential energy due to gravity are equal to the opposite of work done by gravity (PEgrav = -Wgrav). If a spring is exerting a force of 7.23 N at a displacement of -9.65 m, what is the spring constant for that spring (in N/m)? (A) .642 (B) .749 (C) .813 (D) .893
