Energy

Energy n. Energy work. n. Energy is the ability to do causes motion and causes changes in matter.

There are many kinds of energy: M - Mechanical n E - Electrical n L - Light n T - Thermal n S - Sound n

Mechanical Energy n. The energy related to the motion of an object

Mechanical Energy n. Potential Energy – stored energy. n. The object is not moving.

Mechanical Energy n. Kinetic Energy – energy caused by motion n. The object is moving.

Electrical Energy n. Electricity is produced when electrons move from one place to another place.

Light Energy n Light energy uses waves to travel through space. Sources of light can be a light bulb, a fire, the sun, a candle, or a flashlight.

Thermal Energy n The increase or decrease of heat. Heat is caused when particles in matter move. As particles move more quickly, the object gets hotter.

Thermal Energy

Sound Energy n Sound is created by vibrations and travels in waves. Can travel in different media (solid, liquid, gas). n Force must be applied to make an object vibrate. n The vibrations from a vibrating object spread out in waves. The waves carry energy from the sound source outward in all directions.
