Act 2.1: Forms of Energy Forms of energy related to the energy of motion are associated with moving objects, atoms, and molecules. Mechanical Energy of Motion: Moving objects exhibit mechanical energy of motion, also called kinetic energy. Thermal Energy: Energy of motion occurs within an object as its atoms and molecules vibrate randomly. Thermal energy is the unorganized energy of motion of vibrating objects too small to see. Sound Energy: When atoms and molecules vibrate in an organized way, their vibrations may travel as a sound wave. Sound is the transmission of vibrations through a solid, liquid, or gas by vibrating atoms or molecules. 2-2
