Force and Energy

Jason climbs a ladder to hang lights on his house.  What type of energy does he use?

• Potential Energy
• Mechanical Energy
• Thermal Energy
• Sound Energy

Which of the following is NOT an example of a force?

• Gravity
• Magnetism
• Conductors
• Friction

Which of the following is an example of electrical energy and sound energy?

• Broom
• iPhone

An electrician wears rubber gloves when he is working.  Why does he do this?

• The gloves are good conductors that will protect him.
• Rubber is an insulator to protect him.
• They are part of his uniform.
• Rubber is a material that will let heat pass through.

What is true of conductors?

• They slow the transfer of energy.
• They allow heat and/or electricity to pass through.
• They are made of rubber.
• They are used to create open circuits.

Jill notices that when she puts plastic between a magnet and paper clip, the force isn't as strong.  Why?

• increasing distance, decreases the power of magnetism
• decreasing distance, decreases the power of magnetism
• Magnetism doesn't work with material between the magnet and object
• Magnets aren't attracted to paper clips

Which material is not an electrical insulator?

• Rubber
• Plastic
• Wood
• Copper

What type of circuit is shown?

• Open Circuit and Series Circuit
• Closed Circuit and Series Circuit
• Open Circuit and Parallel Circuit
• Closed Circuit and Parallel Circuit

Which material is considered a thermal conductor, but an electrical insulator?

• Metals
• Glass
• Plastic
• Aluminum

The water wheel uses the moving water to produce electricity for the cabin.  What forms of energy are used?

• Mechanical and Sound
• Sound and Light
• Thermal and Light
• Mechanical and Electrical
