### Journal CH 6-1 Types of Energy

• I can:

• Describe what energy is

• List different forms of energy

• Describe how energy & matter are related

• Describe ways in which energy is transferred Describe ways in which energy is transformed Apply the law of conservation of energy to specific situations

32

• 0 grams

• 0.1 – 2 grams

• More than 2 grams, but less than a few pounds

• More than a few pounds

You burn gasoline in your car’s engine. How much energy is lost when the fuel tank is all used up (burned up)?

32

• 100%

• 80-99%

• 60-79%

• 40-59%

• 20-39%

• 1-19%

• Energy is lost when the fuel tank is all used up (burned up)?:

• Required to produce a change, do work, or to cause things to happen

• Has no mass

2. Energy Types: is lost when the fuel tank is all used up (burned up)?

• Potential

• Thermal: Heat

• Light

• Chemical

• Electrical

• Kinetic

• Sound

• Nuclear

3. is lost when the fuel tank is all used up (burned up)?Potential Energy:

• Stored Energy

• Energy is present even when it isn’t being used

4. Types of Potential Energy:

• Gravitational: Height of an object

• Greater elevation = more gravitational potential energy

• Chemical: uneaten food, unused gasoline, unused chemical, etc

• Elastic: rubber band, springs, etc.

5. Kinetic Energy: Energy of motion

• More kinetic energy = faster speed

6. Thermal Energy: is lost when the fuel tank is all used up (burned up)?

• Never decreases.

• Once it is released by a heater into the atmosphere it doesn’t go back into the heater.

• Increases when the heat is on

• Stops when heat is turned off.

7 is lost when the fuel tank is all used up (burned up)?. Friction force:

• NOT a type of energy

• Friction makes heat

• Where the two palms of your hand are striking one another

8. Energy Transfer: When energy is transferred from one object to another object

• Example: Energy is transferred from the bat to the ball

9. Energy Transformation: When energy is changed from one type of energy to another

• Example: Energy is transformed from electrical energy to light energy in a light bulb

10. Conservation of Energy: is lost when the fuel tank is all used up (burned up)?

• Energy cannot be created or destroyed

• Total amount of energy remains the same

• If energy increases somewhere it must decrease somewhere else

Is friction energy? is lost when the fuel tank is all used up (burned up)?

32

• Yes

• No

Friction is a force (push/pull on an object. It is not energy.

It is caused by energy (kinetic energy of two objects striking each other)

AND…the motion is transformed into another type of energy (thermal)

You take a step with your feet. The bottom of your heal strikes the ground. What is the energy transformation?

• Friction transforming into thermal on the bottom of your feet

• Thermal transforming into kinetic energy on the ground

• Kinetic transforming into thermal on the heel of your shoe

PS3A: Energy Basics is lost when the fuel tank is all used up (burned up)?

• I can:

• Describe what energy is (review)

• List different forms of energy (review)

• Describe how energy & matter are related

• Describe ways in which energy is transferred (review…but with the specific energies we are studying)

• Describe ways in which energy is transformed (review…but with the specific energies we are studying)

• Apply the law of conservation of energy to specific situations

Rate your ability on the following learning target is lost when the fuel tank is all used up (burned up)?:

32

• F: I don’t understand how.I make lots of mistakes.

• D: I have a below average understanding. I can do it, but make many mistakes.

• C: I have an average understanding.I can do some of it, but I make several mistakes.

• B: I have an above average understanding. I could do it myself without help, but I sometimes make a few mistakes.

• A: Excellent understanding. I could teach how to do this to someone else. I rarely make mistakes.
