Lesson 3.4 Energy Change and Conservation

What is the law of conservation of energy?

• matter cannot be created or destroyed

• energy can be created or destroyed

• energy cannot be created or destroyed but can be changed from one form to another

• energy cannot be created or destroyed and cannot be changed from one form to another

When energy is transferred, does the type of energy change?

• Yes, the type of energy stays the same and is transferred from object to object.

• No, the type of energy stays the same and is transferred from object to object.

• Yes, the type of energy changes and energy transforms from one type to another.

• No, the type of energy changes and energy transforms from one type to another.

True or False: During energy transfer, the total amount of energy stays the same.

• True, the amount of the types of energy can change, but the total amount of energy does not.

• True, the total amount of energy does not change, it is only moves from object to object.

• False, the amount of the types of energy can change, but the total amount of energy does not.

• False, the type of energy does not change, but the total amount of energy can change.
