Energy Transfers and Transformations
![Page 2: Energy Transfers and Transformations. Two “categories” of energy but many “forms” Kinetic energy (energy in motion) Objects moving (people, cars, rivers,](https://reader035.vdocuments.net/reader035/viewer/2022062720/56649f125503460f94c25fb0/html5/thumbnails/2.jpg)
Two “categories” of energy but many “forms”
Kinetic energy (energy in motion)
• Objects moving (people, cars, rivers, wind, etc…)
• Heat energy (thermal)• Light energy (radiant)• Sound energy• Electricity down a wire or
lightning bolt thru the air
Potential energy(energy being stored up)
• Mechanical- stored in springs and bands being stretched or squeezed
• Gravitational- Stored by raising objects high in the air (away from “rest”).
• Chemical- stored in food, batteries, explosives…
• Nuclear- stored in the nucleus of atoms and their particles.
