Study Notes

Energy Transformations

Energy is the ability to do work.
The total energy in the universe is constant, but it transforms between different forms.
Examples of energy forms include: thermal, radiant, chemical, electrical, nuclear, and mechanical.

Examples of Energy Transformations

Campfire: Near a campfire, both thermal (heat) and radiant (light) energy are produced.
Batteries: Chemical energy in batteries is converted to electrical energy.
Electrical Devices: When a plug is connected to a power supply, electrical energy powers the device and produces other forms of energy, like light, sound, or heat.
Nuclear Fission: Splitting the nucleus of an atom (fission) releases nuclear energy.
Mechanical Energy: Objects have potential energy (due to position) and kinetic energy (due to motion).
