What is the energy of motion?
Kinetic energy
Kinetic energy plus potential energy gives us what?
mechanical energy
What does our body use for energy
Food
What is it called when sound and light bounce off of objects so we can see and hear them?
Reflection
What is the difference between a conductor and a insulator
A conductor is a material where electricity can flow through it
An insulator is a material that slows or stops the flow of electricity
What is the purpose of heat energy
We use heat energy to cook and iron clothes
What is refraction?
Light waves bend as they go through different forms of matter
What object could we see kinetic and potential energy working together
Roller coaster
What is the looped path of conductors through which electric current flows
A circuit
A circuit must be what in order to work?
THe circuit must be closed
What is a device that uses energy motion
Car, electric toothbrush, and an electric lawn mower are all examples
Provide two types of conductors
water and metal are conductors
Why will two balloons push away from each other if they are statically charged?
The negative side on each will push on the balloons causing them to go in opposite directions
Explain how the steel wool experiment worked
The steel wool completed the circuit causing the battery to give off heat. The heat caused the wool to ignite on fire
Provide two types of insulators
wood and rubber are insulators
