What is energy? Energy is the ability

to do work.

Page 3: Energy

In the Human Body Unit, you learned thatenergy is essential for the functioning of all

body systems.

Page 4: Energy

In the Ocean Unit, you learned that

the sun is the primary source of all energy.energy is the driving

force of the food web.

Page 5: Energy

In the Wise Use of Resources Unit you

learned thatobtaining, transforming, and distributing energy affects the environment.

Page 6: Energy

Energy is classified asPotential Energy

Page 7: Energy

Kinetic Energyor

Page 8: Energy

Potential Energy is stored energy.

Page 9: Energy

Kinetic Energy is energy due to the

motion of an object.

Page 10: Energy

Imagine yourself on a trampoline.

The trampoline has a large amount of potential energy.

As the trampoline pushes you upward,

it is starting to transfer its potential

energy to you.

The instant you leave the trampoline

you have kinetic energy.

Page 11: Energy
Page 12: Energy

Some objects have potential energy because of their

position.

Page 13: Energy

The boulder on top of the mountain

has potential energy.

Page 14: Energy

When the boulder

begins to roll down

the mountain,

the potential energy is changed

into kinetic

energy.

When it reaches

the bottom of

the mountain,

it stops rolling.

Page 15: Energy

Some substances have potential

energy because of their chemistry.

Baking soda and vinegar have

potential energy because of their

chemistry.

When the two chemicals are mixed, a gas is formed and the

mixture begins to bubble and fizz.

When the chemicals are combined the

potential energy is transformed into kinetic energy.

A rocket on a launching pad has what type of

energy? POTENTIAL!!!!!!

Page 27: Energy

When the rocket is launched, the potential energy is changed

to ...Kinetic Energy!!!!
