ACTIVITY 3 Problem Solving Gravitational Potential Energy and Elastic Potential Energy Energy is the ability to produce changes in matter. It has two states, the kinetic energy and potential energy. Kinetics energy has 3 forms, vibrational, rotational, and translational, While potential energy has 3 types, gravitational, chemical, and elastic potential energy. Gravitational PE is the energy stored because of its height and elastic PE is the energy stored in elastic materials as the result of their stretching or compressing. nga Read, analyze, and solve the following problems using the GUFSA template.
