TYPES OF ENERGY

Mechanical, Electromagnetic, Electrical,

Chemical and Thermal

Slide 2

What is Mechanical Energy?

Energy due to a object’s motion (kinetic) or position (potential).

The bowling ball has mechanical energy.

When the ball strikes the pins, mechanical energy is transferred to the pins!

Slide 3

Examples of Mechanical Energy

Slide 4

What is Electromagnetic Energy?

Light energy

Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands

Slide 5

What is Electrical Energy?

Energy caused by the movement of electrons

Easily transported through power lines and converted into other forms of energy

Slide 6

What is Chemical Energy?

Energy that is available for release from chemical reactions.

The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.

Slide 7

Examples of Chemical Energy

Slide 8

What is Thermal Energy?

Heat energy

The heat energy of an object determines how active its atoms are.

A hot object is one whose atoms and molecules are excited and show rapid movement.

A cooler object's molecules and atoms will show less movement.
