TYPES OF ENERGY ENERGY TRANSFORMATION 7 different types

TYPES OF ENERGY & ENERGY TRANSFORMATION

7 different types ◦ Mechanical ◦ Electrical ◦ Light ◦ Thermal ◦ Sound ◦ Chemical ◦ Nuclear

Mechanical Energy ◦The energy of movement. Mechanical energy includes both kinetic AND potential energy.

Electrical Energy ◦A form of energy that is produced when electrons move from place to place.

Light Energy ◦A form of energy that travels in waves and can move through empty space where there is no air.

Thermal Energy ◦The energy of moving particles in a substance; also called heat energy.

Sound Energy ◦A from of energy produced by vibrations between objects

Chemical energy ◦The energy that is stored in bonds of chemical compounds. ◦Some bonds have more energy than others

Nuclear energy ◦The energy in the nucleus of an atom. ◦ 2 types ◦Nuclear Fusion-Combining two or more smaller atoms to form a larger atom ◦Nuclear Fission-Breaking down a larger atom into two smaller atoms.

Law of Conservation of Energy ◦Energy cannot be created or destroyed, only transferred. ◦A change from one type of energy to another is called an energy transformation.

Example ◦A toaster transforms electrical energy into thermal energy to toast your bread. ◦Your body transforms chemical energy (from food) into mechanical energy to walk/move.
