Agenda 1/27/10 Forms of Energy (#1). Energy Conversion. Homework: Forms of Energy Worksheet (#2) Life Science #6 due next Tuesday
Forms of Energy Mechanical Energy: Definition energy associated with any type of motion. Examples: Wind, water in a waterfall, running, sound (vibration of matter).
Heat Energy: Definition The internal motion of particles in matter. Examples: Rubbing you hands together converts mechanical energy into heat energy. * Heat flows from a warm object to a cooler object.
Chemical Energy: Definition Energy found in chemical bonds, releases when bonds are broken. Examples: Digesting food, when fuel is ignited chemical energy is released.
Electromagnetic Energy: Definition Moving electric charges. Examples: Electricity, light, radio waves.
Nuclear Energy: Definition Energy produced from the splitting or fusion of an atom’s nucleus. Examples: Nuclear power plants, energy from the sun.
Law of Conservation of Energy Energy can not be created or destroyed (it just changes into another form – conversion). Example: chemical energy in gasoline is transformed into mechanical and heat energy in an engine.
