energy and heat

The ability to do work is

• power
• energy
• thermal
• kinetic

Heat energy is also called

• electrical energy
• chemical energy
• light energy
• thermal energy

In a science project, Evan and Amanda are exploring the concept of Electrical Energy, which is:

• energy caused by the vibrations of an object

• energy caused by changes in the nucleus of an atom

• energy of moving electrons

• energy caused by heat

What machine changes electrical energy into light and sound energy, as demonstrated in the science project by Maddy and Xavier?

• battery

• lightbulb

• alarm clock

• apple

What machine changes chemical energy into heat, light and sound energy, as demonstrated in the science project by William and Axel?

• blender

• firecracker

• lightbulb

• apple

Fernanda and Caden connected some wire to a battery and a small bulb to make a simple circuit. Energy from the battery is changed into electricity. What type of energy is stored in the battery?

• chemical

Can energy be created or destroyed, as discussed by Fernanda and Axel in their science project?

• Yes, it can be created.

• Yes, it can be destroyed.

• No, energy is always conserved

• None of these

What is kinetic energy? For instance, when Gavin is running, what type of energy is he primarily using?

• the energy of position or shape

• ability to do work

• the energy of motion

• a dog

Energy that an object has because of its position. Stored energy. Evan and Mason were discussing this type of energy in class. What is it called?

• Kinetic energy

• Potential energy
