Vocabulary
Protons
Positively charged particles
Electrons
Negatively charges particles
If a proton and an electron come close together, they attract
TRUE
What are lighting bolts made up of?
Moving Electrons
What is the abbreviation for Amperes?
A
The smallest particle of an Element that is made up of all matter
Atom
A region around the charged particle or object where the electric force is exerted on other charged particles or objects.
Electric Field
If two of the same charges come close together, they will attract
FALSE
TWO PROTONS AND TWO ELECTRONS REPEL WHEN CLOSE TOGETHER BECAUSE A STRONG FORCE BETWEEN THEM PUSHES THEM AWAY.
Why do charges flow through a circuit?
DIFFERENCES IN POTENTIAL ENERGY
Why does a balloon attract paper?
Static Electricity
Neutral
When there is no charge
Conductor
A material that allows electric charge to move more freely
Voltage is measured in units of amperes.
FALSE
VOLTAGE IS MEASURED IN UNITS OF VOLTS (V)
Why do objects loose charge?
The charge transfers to the air and remains neutral.
What transfers to the balloon when you rub it against something?
ELECTRONS
The continuous flow of charge
Electric Current
Static Electricity
The buildup of charge on an object
Electric fields can be represented by field lines
TRUE
What decreases when you drop an object to the ground?
GRAVITATIONAL POTENTIAL ENERGY
IF YOU WERE TO PICK UP THAT OBJECT BACK TO ITS INITIAL POSITION, THEN THE GRAVITATIONAL PE WILL INCREASE.
A material or an object that does not easily allow heat, electricity, light, or sound to pass through it.
Insulator
A basic property of matter that creates a force and accounts for electric interactions
Charge
Electric Force
The force between charged particles or objects
Protons flow through circuits.
FALSE
ELECTRONS FLOW THROUGH CIRCUITS BECAUSE THEY ARE NEGATIVELY CHARGED, SO THE DIRECTION OF CURRENT IS OPPOSITE TO THE DIRECTION OF ELECTRON FLOW.
Objects become charged by __________ without having to touch.
INDUCTION
The movement of charge that requires direct contact between objects is
Conduction
