Energy Notes
The ability to do work is known as ENERGY
Forms of Energy Kinetic- Energy of Motion All moving objects have kinetic energy Ex: Walking, running, a moving car
Potential- Energy of position or shape, stored energy. Ex: Standing still, soccer ball sitting in the grass
Thermal Energy- The total energy of the molecules in an object. At higher temps molecules move faster. Ex: Ice, water , steam
Chemical Energy- Stored in a substance that can be released when the substance reacts. Ex: Burning wood, digesting food
Electrical Energy- Flow of electricity; energy of moving electrons. Electrons are negatively charged particles and move back and forth in the wires. Ex: Computer , washer, T.V.
Sound Energy- Caused by the vibrations in an object. Ex: Guitar, radio
Light Energy - Caused by the vibrations of electrically charged particles. Examples: Microwave, Lamp
Nuclear Energy – Is caused by changes in the nucleus of an atom. Ex: Sun, atomic bomb, uranium
