100
This particle is the ONLY particle that can move from one object to another
What are electrons?
100
The charge of an object that has 10 protons and 12 electrons.
What is negative 2?
100
Two objects with negative charges will do this.
What is repel?
200
Material in which electric current does not flow freely
What is an insulator?
200
The two particles found in the nucleus
What are protons and electrons?
200
The charge that is left on the polythene rod
What is a negative charge?
200
This material is able to become charged during friction.
What is an insulator?
200
An object with a positive charge, and an object with a negative charge, do this.
What is attract?
300
The result of an imbalance between negative and positive charges in an object
What is Static Electricity
300
This particle has a positive charge and is found in the nucleus.
What is a proton?
300
The electrons in a Van de Graaff generator are created on the rubber band. I place hand on the metal dome. The charge flows in this direction.
What is from the dome to my hand, through my body, and out through the ground?
300
This is the charge of an atom with 25 protons and 20 electrons.
What is positive 5?
300
This is how many volts of electricity the Van de Graaff generator can create.
What is 100,000 to 200,000 volts?
400
One-directional flow of electric charge
What is Direct Current
400
This particle has a neutral charge, and is found in the nucleus.
What is a neutron?
400
A positively charged cloth is used to rub an acetate rod, creating friction. After the transfer of electrons, this charge is left on the acetate rod.
What is a positive charge?
400
Object can become charged through this method, simply by touching an object that is charged.
What is by contact?
400
This is the direction of electron flow when you rub a balloon on your hair.
What is from your hair to the balloon?
500
An electric current which periodically reverses direction and changes its magnitude continuously with time
What is Alternating Current
500
This particle has a negative charge, orbits around the nucleus, and is the active particle in electricity.
What are electrons?
500
The rate at which the electrons flow. (hint. This is the reason we can touch the Van de Graaff. It has a very high voltage, but a very low ______)
What is current?
500
Objects can become charged this way, simply by getting close to a charged object.
What is by induction?
500
The force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
What is friction?
