Study Notes
Types of Energy
- Sound Energy: Energy traveling in waves through matter. Kinetic energy.
- Electrical Energy: Energy from moving electrons. Kinetic energy. Example: Plugging something in.
- Nuclear Energy: Potential energy within atomic nuclei, released in fission or fusion.
- Mechanical Energy: The total potential and kinetic energy in a system. Always remains constant/stays the same.
- Chemical Energy: Energy stored in atomic/molecular bonds.
- Radiant Energy: Energy carried by light waves. Kinetic energy. Example: Solar energy.
- Thermal Energy: Energy related to heat. Kinetic energy.
- Potential Energy: Stored energy. Greatest when an object is furthest from the ground (e.g., top of a hill) — Gravitational Potential Energy.
- Kinetic Energy: Energy of motion. Greatest when an object is moving fastest (e.g., bottom of a hill).
- Law of Conservation of Energy: Energy cannot be created or destroyed, only transformed.
- Energy Transfer: Conversion of energy from one form to another. Often produces heat.
- Electromagnetic Energy: Energy that moves through space as waves, including radio and satellite signals.
