Circuits
What is an open circuit?
A circuit that has a gap or an switch that is up that keeps energy from flowing through it
What is Thermal Energy?
Heat Energy
How do waves move?
Up & Down
Side to Side
Friction
Sound is wave ___________ that can travel through solids, liquids, and gases
vibrations
What is a closed circuit?
A closed circuit is when a circuit is complete with nothing stoping the energy flow.
What is an Insulator?
Something that stops the flow of energy/keeps heat inside
Can waves like water waves or sound waves carry matter (stuff) to different locations?
NO
What force attracts different objects like paperclips and other type of metal objects?
Magnetism
TRUE or FALSE: A battery is a conductor
FALSE. A battery is a power source of chemical energy that can be converted into electrical energy.
What would be a good conductor to place in a circuit in between wires to allow a light bulb to turn on?
paper clip
metal nail
What is a Conductor?
Something that allows energy to flow through easily.
How can energy transfer when someone plays a piano?
The person uses mechanical energy to produce sound energy by playing the keys of the piano
What force pulls you toward the center of the Earth?
Gravity
What kind of energy involves motion?
If a switch is up within a circuit, how would you describe the circuit?
It is an open circuit
What is Mechanical Energy?
Energy that is moving or caused by movement.
How does energy transfer when a person plays the drums?
The person uses mechanical energy to produce sound energy by hitting the drums.
If Friction a contact force or a non-contact force?
Contact Force
Relative density is an objects ability to do what?
Sink or float
What could I add into a circuit that would allow me to control when the electrical current would travel through to light a bulb?
A switch
Describe what Energy Transfer is
Energy transfer is when one kind of energy is transferred or given to someplace else (mechanical --> sound when playing a piano).
Can sound travel through solid matter?
YES
What does non-contact force mean?
Non-contact force means that objects do not have to be in contact in order for the force to work. It can work from a distance.
What is the main difference between a mixture and a solution?
Mixtures can be easily separated and solutions cannot.
