Force, Energy, & Motion
How fast an object is moving is called...
What is speed?
A flow of electric charge or the flow of electrons in a wire; also creates a magnetic field
What is an electric current?
Name which number is an open or closed circuit
1. A circuit that allows the movement of electrical energy; 2. A circuit that prevents the movement of electrical energy
What are: 1. a closed circuit; 2. an open circuit?
Materials that allow an electric charge to pass through easily?
What are conductors?
A device used to protect buildings from damage during electrical storms. It is usually on top of tall buildings
What is a lightning rod?
Name whether it is potential or kinetic
1. Energy of motion; 2. Stored energy
What are: 1. kinetic energy; 2. potential energy?
Electricity that is seen as a spark after objects rub against each other
What is static electricity?
The current only moves along one path in this type of circuit.
What is a series circuit?
A substance that conducts very little electricity
What is an insulator?
"My scientific experiments with a kite and key proved that lightning is a form of electricity." Who am I?
What/who is: Benjamin Franklin?
Any push or pull that causes an object to move, stop, or change its speed or direction is called
What is force?
When static electricity is discharged (given off) in the atmosphere, it creates:
What is: lightning
The current is able to move along more than one path in this type of circuit.
What is a parallel circuit?
3 examples of insulators
What are: plastic, glass, wood, rubber? (Any 3)
"I designed the world's first electric power stations, thereby making electric power available to millions."
What/who is: Thomas Alva Edison?
Resistance to motion created by two objects moving against each other is called
What is friction?
The pathway taken by an electrical current
What is a circuit?
This type of circuit runs the electric appliances in your home.
What is: a parallel circuit?
3 examples of conductors
What are: iron, copper, aluminum, gold, steel? (Any 3)
"I invented the incandescent lightbulb."
What/who is: Thomas Alva Edison?
The form of energy that is produced when friction occurs
What is: heat?
Electrons have what kind of charge?
What is: Negative
Electricity is caused by the movement of what?
What are: electrons
Anything that slows down the flow of electric charge in a material; also changes electrical energy to heat and light
*The graphite in a pencil from Bill Nye yesterday was an example
What is: resistance?
(resistor)
"By supplying current to a wire that was wrapped around a piece of iron, I invented the electromagnet."
What/who is: Michael Faraday?
