1. CHAPTER 17
ENERGY

2. ENERGY
●
ABILITY TO CAUSE CHANGE OR DO
WORK.
●
EVERY CHANGE INVOLCES ENERGY
AND ENERGY IS RELATED TO WORK.
●
ENERGY AND WORK USE SAME UNIT
OF MEASUREMENT THE JOULE(J)

3. 6 FORMS OF ENERGY
●
KINETIC
●
POTENTIAL
●
CHEMICAL
●
NUCLEAR
●
THERMAL
●
ELECTRICAL

4. KINETIC ENERGY
● Mechanical energy of a moving object
● Example: Ball rolling across the floor

5. POTENTIAL ENERGY
● Mechanical energy due to position
● Example: book sitting on your desk.

6. CHEMICAL ENERGY
●
Is stored in the bonds between atoms
●
Examples:
●
the foods we eat gives us energy.
●
Cars use energy used in gasoline

7. NUCLEAR
●
When atoms break apart.
●
Example: Nuclear power plants

8. THERMAL ENERGY
●
Moves from one object to another as
heat.
●
Example: Friction

9. Electrical Energy
●
Results from the movement of electrons
●
Example: TVs and lights

10. Energy Changes
● From one form to
another
● All forms of energy
can be used to
create forces to do
work
● Each type of
energy can be
changed into
thermal energy.

11. Law of Conservation
●
Energy is not created or destroyed It is
conserved
●
Example: Bouncing a ball the ball stops
bouncing and the floor absorbs the
energy of the ball.
