Knowledge and Skills Statement
Energy manifests in multiple phenomena, such as motion, light, sound, electrical and magnetic fields, and thermal energy. Energy can be modeled as either motions of particles or as stored in force fields (electric, magnetic, gravitational) that mediate interactions between particles. The total amount of energy in a system does not change, but it can be transferred between objects within the system.
Images like these can be useful when working with students to help them understand transverse and longitudinal waves.
