What is friction between the road and tires called?
Traction
What is the flow of electrons through a conductor?
Electricity
What is the force that slows motion when two objects rub against each other?
Friction
Electrons move from what to what direction?
Negative to positive
Electric cars use what in order to make the motors turn?
Electricity
What is the circular path electrons travel in a negative to positive direction?
Circuit
What is a material that allows electrons to pass through?
Electronic conductor
What are the paths called that electrons travel in the circuit?
