What is static electricity caused by?
A balance of power
A balance of positive and negative charges
An imbalance of positive and negative charges
An imbalance of protons and neutrons
Two objects with LIKE elecrical charges will
attract each other
even out in the end
repel each other
cause a spark
If an object has a higher number of electrons than protons on its surface, what type of charge does it have?
A positive charge.
A negative charge.
A neutral charge
No charge at all
What happens after rubbing your shoes on the carpet, gaining a negative charge and then you touch a metal doorknob?
The doorknob sends a burst of electric current into your body
Electrons go from your finger into the doorknob
The doorknob sends millions of electrons into your finger
Our finger becomes negatively charged
An object becomes postively charged when which of the following occurs?
loses electrons
gains electrons
loses protons
gains neutrons
Rubbing wool on a balloon is an example of static charge build up created by....
conduction
friction
induction
hairduction
True or False:
In static electricity, charges build up on an object, but they do not flow continuously.
True
False
You move a soda can with a negatively charged balloon without touching the soda can. Why does the can move?
It has a positive charge, and attracts to the negative balloon since opposites attract.
It has a neutral charge and attracts to the negative balloon since the negative charges in the can move away from the balloon.
It has a negative charge and since it repels the negative balloon, it is attracted to the balloon. Does this even make sense? Probably not.
Neither object is charged, and the can must be on an incline to be moving towards the balloon.
This type of charge transfer occurs when we touch a metal object with a charged object.
Conduction
Induction
Friction
Polarization
These elementary particles exist within the nucleus of the atom. (Select all that apply)
Proton
Neutron
Electron
Citron
This is the process that involves removing excess charge from objects.
Induction
Grounding
Production
Batman
The non-contact separation of charge in a neutral object is called...
conduction
friction
polarization
This particle moves from object to object during static electricity charge transfers.
Electrons
Protons
Neutrons
Quarks
Citron rubbed two balloons with a piece of wool. What will happen when the balloons are brought near each other?
The balloons will repel each other.
The balloons will attract each other.
The balloons will become positively (+) charged.
The balloons will pop.
The Coulomb is the unit for:
Charge
Force
Distance
Mass
Coulomb’s law states that the force between two charged objects will __________ when the magnitude (value) of the object’s charge increases.
increase
decrease
stay the same
first increase, then decrease
What will be the units of F (or Fe)?
Newtons
Meters
Coulombs
Joules
What does Fe stand for?
the electrostatic force
the symbol for iron
the constant for the charges
the charges of the particles
What does q measure?
the distance between the two charged objects
the amount of charge carried by the object
the amount of force between two charged objects
According to Coulomb's Law, when the distance increases, the electrostatic force ____________.
increases
decreases
remains unchanged
has no relationship to distance
What happens to the force between two charged objects when you double the distance between them?
it doubles
it is cut in half
it quadruples
it is cut by 1/4
If one of the charges doubles, what happens to the force?
it doubles
it gets cut in half
it quadruples
it is cut by 1/4
