Make Up of Energy

Energy is all around you! You hear energy as sound, you see energy as

light, you can feel energy in wind Living organisms need energy for growth and

movement. You use energy when you kick a ball, catch a ball,

or even lift a grocery bag.

THEREFOR: ENERGY IS THE ABILITY TO DO WORK.

Other Forms of Energy

5 main forms of energy:

Mechanical Energy Heat Energy Chemical Energy Electrical Energy Gravitational Energy

Mechanical Energy Mechanical

Energy: is the energy of motion that does the work.

Examples: Water in a waterfall Wind Moving Vehicles Sound

Heat Energy Heat energy: is

energy that is pushed into motion by using heat.

Examples: Friction Sun (also known as

thermal energy) Radiation Fire

Chemical Energy Chemical

Energy: is energy caused by chemical reactions. A good example of chemical energy is food when it is cooked.

Examples: Digesting food,

bonds are broken to release energy for the body to store and use

Photosynthesis Using energy to play

sports

Electrical Energy Electrical

Energy: is when electricity creates motion, light or heat.

Examples: Power lines carry

electricity Electrical motors Light (X-rays, radio

waves, laser light etc.)

Lightning

Gravitational Energy Gravitational

Energy: is motion that is caused by gravity.

Examples: Water that is pulled

down a waterfall The pull felt when

you jump up that forces you to come back down.

Learning Goals

What is energy? Can energy be transferred from one

object to another? What are the different forms of energy?

States of Energy

There are two states of energy:

Potential Energy

 Potential Energy: is stored energy. Examples of potential energy are oil sitting in a barrel, or water in a lake in the mountains. This energy is referred to as potential energy, because if it were released, it would do a lot of work.

Kinetic Energy

Kinetic Energy: is energy that is in motion. Moving water and wind are good examples of kinetic energy. Electricity is also kinetic energy because even though you can't see it happen, electricity involves electrons moving in conductors.

The Lighter Side of Energy What would a barefooted man get if he

steps on an electric wire?(Answer) A pair of shocks.

Wind power is very popular because it has a lot of fans.

What would you call a power failure?(Answer) A current event.

What's the best way to charge a car battery?(Answer) With a credit card.

Assignment!!!

Identify the 5 TYPES of energy. List at least two different examples of

the 5 main TYPES of energy. State the two FORMS of energy. List an example for each of the FORMS

of energy
