TYPES OF ENERGY

Page 2: TYPES OF ENERGY Energy Ability to do work Can not be created or destroyed Can be transformed from one form to another

Energy• Ability to do work

• Can not be created or destroyed

• Can be transformed from one form to another

Page 3: TYPES OF ENERGY Energy Ability to do work Can not be created or destroyed Can be transformed from one form to another
Page 4: TYPES OF ENERGY Energy Ability to do work Can not be created or destroyed Can be transformed from one form to another

Potential Energy• Stored energy

• Has the potential to move

• Stretched out rubber band

Page 5: TYPES OF ENERGY Energy Ability to do work Can not be created or destroyed Can be transformed from one form to another

Kinetic Energy • Due to its motion

• Releasing the rubber band

Page 6: TYPES OF ENERGY Energy Ability to do work Can not be created or destroyed Can be transformed from one form to another

What is Mechanical Energy?

o 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!

Examples of Mechanical Energy

Page 8: TYPES OF ENERGY Energy Ability to do work Can not be created or destroyed Can be transformed from one form to another

Light Energy• Energy that is made of electro-

magnetic radiation and travels in a straight path.

Page 9: TYPES OF ENERGY Energy Ability to do work Can not be created or destroyed Can be transformed from one form to another

What is Thermal Energy?o Heat energy

o Measured by heat

o The heat energy of an object determines how

active its molecules 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.

Solar EnergyEnergy from the Sun

Solar Panels

Page 11: TYPES OF ENERGY Energy Ability to do work Can not be created or destroyed Can be transformed from one form to another

What is Electrical Energy?o Energy flowing

through an electric circuit

o Energy caused by the movement of electrons

o Easily transported through power lines and converted into

other forms of energy

Sound energy • Energy in which you can hear and

that travels in vibrating waves through the air. It's the energy present in a sound wave.
