They are the negatively charged particles in a material.
What are electrons?
100
The charge on an electroscope if it is touched by a positively charged object.
What is a positive charge?
100
A material that can easily transfer electrons from atom to atom.
What is a conductor?
100
A device demonstrated in class that separates a large amount of charge.
What is a Van De Graaff generator?
100
It is the induced charge on the surface of the Earth just before lightning strikes.
What is a positive charge?
200
The list of materials that indicates a material's tendency to gain or lose electrons.
What is the electrostatic series?
200
When a negatively charged object is brought near the ball of an electroscope, this is the charge on the metal leaves.
What is negative?
200
It is an isolated conductor with a sharp point located at the top of tall buildings.
What is a lightning rod?
200
The effect on electric force when charged objects are moved away from each other.
What is a decrease in electric force?
200
It reduces friction on the clothes in the dryer.
What is fabric softener?
300
These kinds of charges attract.
What are different charges?
300
It is the charge on the cotton after rubbing nylon and cotton together.
What is a negative charge?
300
When a negatively charged object is brought near the ball of an electroscope, this is the charge on the metal leaves.
What is negative?
300
The unit used to measure electric charge.
What is a coulomb?
300
In order for the hegatively charged ash particles in the electrostatic precipitator to stick to the metal plates, this must be the charge on the metal plates.
What is a positive charge?
400
The charge on an object with fewer electrons than protons.
What is a positive charge?
400
You shuffle across the carpet and when you touch the metal doorknob you feel a shock. It's what causes the shock.
What is a transfer of electric charge?
400
A substance in which the electrons are tightly bound to the atoms and cannot freely move to neighbouring atoms.
What is an insulator?
400
Two ways to increase electric force.
What is decreasing distance or increasing charge?
500
Famous scientist who proved that lightning is an electrical discharge.
Who is Benjamin Franklin?
500
A negatively charged object is brought near the left side of a metal sphere. A grounding wire is attached to the right side of the metal sphere. Later, the negatively charged object and the grounding wire are removed. This is the charge left on the metal sphere.
What is a positive charge?
500
When a metal sphere is given a charge, the charge spreads out evenly over the surface of the sphere. It is the cause of this.
What is the repulsion of like charges?
500
The threads taped to the top of the Van de Graaff generator in last day's demo stood up and spread out when the VDG was turned on. It is the cause of this.
