Force and Motion
How fast/ Slow an object is movinng
Speed
A flow of electric charge or the flow of electrons in a wire; also creates a magnetic field
electric current?
1. A circuit that allows the movement of electrical energy; 2. A circuit that prevents the movement of electrical energy
1. a closed circuit; 2. an open circuit
Materials that allow an electric charge to pass through easily?
Conductors
A device used to protect buildings from damage during electrical storms
What is a lightning rod?
1. Energy of motion; 2. Stored energy
1. kinetic energy; 2. potential energy?
Electricity that is seen as a spark after objects rub against each other
Static Electricity
The current only moves along one path in this type of circuit.
a series circuit
A substance that conducts very little electricity
Insulator
Who said
"My scientific experiments proved that lightning is a form of electricity."
Benjamin Franklin
Any push or pull that causes an object to move, stop, or change its speed or direction
A force
Complete Loop
The current is able to move along more than one path in this type of circuit.
a parallel circuit
3 examples of insulators
Glass, Wood, Plastic, Rubber, or Stone
I designed the world's first electric power stations, thereby making electric power available to millions."
Thomas Edison
Resistance to motion created by two objects moving against each other
Friciton
The pathway taken by an electrical current
Circuit
This type of circuit runs the electric appliances in your home (open or close, series or parallel)
A closed parallel circuit
2 examples of conductors
Metal, Water
"I invented the incandescent light."
Thomas Edison
The forms (2) of energy that is produced when friction occurs
Static electricity and heat
The kind of electricity that works in your home or when you hook up a circuit with batteries
current electricity
3 ways electrical energy can be transformed
Thermal/ heat, Radiant/ light, & Mechanical/ moving energy
Anything that slows down the flow of electric charge in a material;
also changes electrical energy to heat, light, or motion
Resistance
"By supplying current to a wire that was wrapped around a piece of iron, I invented the electromagnet."
Michael Faraday
