Lesson 3-4 Review

Which forms of energy can be transformed into other forms of energy?

• Only kinetic energy can be transformed into other forms of energy.
• All forms of energy can be transformed into other forms of energy.
• None of the forms of energy can be transformed into other forms of energy.
• Only potential energy can be transformed into other forms of energy.

How many times can energy be transformed?

• Energy can only transform once.
• Energy can transform once or many times.
• Energy can transform only 3 times.
• Energy can transform only 5 times.

What is one type of common energy transformation?

• One common type of energy transformation involves mechanical energy changing to kinetic energy.
• One common type of energy transformation involves chemical energy changing to electrical energy.
• One common type of energy transformation involves electrical energy changing to gravitational potential energy.
• One common type of energy transformation involve potential energy changing to kinetic energy.

Are energy transformations and energy transfers the same thing? Why or why not?

• Yes, because both take place when one form of energy changes to another.
• No, because energy transformation occurs when one form of energy changes into another, while energy transfer takes place when energy moves from one object to another.
• Yes, because both take place when energy moves from one object to another.
• No, because transformations only take place when energy moves from one object to another.

What is the law of conservation of energy?

• The idea that energy either moves from one object to another or changes forms, but no energy is created or destroyed.
• The idea that energy is created after a series of transformations and transfers.
• The idea that energy is destroyed after a series of transformations and transfers.
• The idea that energy is conserved when an object has potential energy.

According to the law of conservation of energy, what happens to energy?

• Energy is destroyed.
• Energy is created.
• Energy is conserved.
• Energy transforms into thermal energy.

What can be said about energy after it is transformed or transferred?

• The total amount of energy is destroyed.
• The total amount of energy changes depending on an object's weight.
• The total amount of energy doubles.
• The total amount of energy in a system does not change.

What happens to energy in any type of wave?

• Energy moves the matter from side to side.
• Energy is transformed from potential energy to kinetic energy.
• Energy passes through matter without moving the matter to a new place.
• Energy is transferred from the wave to the surrounding air.

What happens to matter when energy passes through it?

• The matter vibrates, but ends up back where it was.
• The matter changes from a liquid to a solid.
• The matter changes temperature.
• The matter is rearranged into a gas.

What happens to the energy in an ocean wave?

• The energy is carried further out into the ocean.
• The energy is destroyed by the marine animals in the ocean.
• The energy is released and the energy is transferred to the shore.
• The energy creates more waves that lead to a tsunami.
