Energy Unit

The law of conservation of energy states that when one form of energy is transformed into another, energy is:

• Not created or destroyed
• Destroyed
• Created
• Turned in to Peanut Butter

Which type of energy increases when you compress a spring?

• elastic potential energy
• kinetic energy
• radiant energy
• sound energy

Elastic potential energy is energy stored in an object, such as a spring, due to the object being stretched or compressed. In which position is it most likely that the spring has lost its elastic potential energy?

• W

• Y

• X

• Z

Energy stored because of gravity is called:

• Gravitational Potential Energy

• Kinetic Energy

• Mechanical Advantage

• Chemical Energy

At which point does the ball has the greatest gravitational potential energy (GPE)?

• A

• G

• D

• C

• G

Which would have the LEAST gravitational potential energy (GPE)?

• A ball sitting on the ground

• Moon viewed from the Earth

• An airplane flying 30,000 feet above the ground

• A rock sitting on top of Mt. Everest

How could you increase the gravitational potential energy of an object without changing its mass and gravity?

• Make the object larger

• Lower the object towards the ground

• Raise the object farther off the ground

• Allow the object to roll on the ground

Which picture is NOT an example of Chemical PE?

• 
• 
• 
• 

What potential energy is this graph representing?

• Electric

• Elastic

• Magnetic

• Gravitational

Which piece of evidence BEST represents Chemical PE being released?

• a rubber band flung a far distance

• an apple falling from a tree

• 2 magnets repelling

• water temperature increasing
