a) Conduction
b) Induction
c) Friction
d) None of the above
c) Friction
True or False: Static electricity is the flow of electric charge through a conductor.
false. Static electricity refers to a buildup of electric charge on an object, not the flow of charge through a conductor
True or False: Lightning is an example of static electricity.
True
A balloon is rubbed against a wool sweater
1. induction
2. conduction
3. friction
3. friction
Which part of the atom is NOT found in the nucleus
Proton
Neutron
Electron
Electron
True or False: When two objects are rubbed together and become charged, one object gains electrons while the other loses electrons.
True. When two objects are rubbed together, electrons are transferred from one object to the other, causing one object to gain electrons (becoming negatively charged) and the other to lose electrons (becoming positively charged).
What is the charge of an electron
Positive
Negative
Neutral
If a negative charge is near a positive charge, the negative charge will be pushed ________
Toward the positive charge
Away from the positive charge
To the center
1. Toward the positive charge
4. Which of the following materials is likely to gain electrons when rubbed against another material (as in, which material likes electrons)?
a) Glass
b) Plastic
c) Metal
d) Wood
b) Plastic

Your hair lost protons
Your hair gained electrons
Your hair lost electrons
Your hair gained protons
3. Your hair lost electrons
A neutral piece of paper is touched by a charged straw
1. induction
2. conduction
3. friction
2. conduction
A charged balloon repels another charged balloon, this happens because the balloons have ___________
The same charge
Opposite charges
A twitter fight
The same charge
The what is the name of the force that causes the two balloons to push away?
Strong force
Electrostatic force
THE force
Centripetal force

This type of charging occurs when a charged object touches a neutral object and transfers its charge.
1. induction
2. conduction
3. friction
2. conduction

2. Human hair
3. Vinyl
4. Plastic
2. Human hair
Which of the following materials is likely to gain electrons when rubbed against another material?

c) Coulomb
d) Ohm
c) Coulomb
When a student finishes the laundry and takes his clothes out of the dryer, he discovers that his cotton sock is sticking to his wool sweater due to static electricity. Use the image above to explain.
Why are the articles of clothing sticking together?
static electricity generated by the friction of the clothes rubbing against each other in the dryer, causing an imbalance of electrical charges where one item becomes positively charged and the other negatively charged, resulting in an attractive force that keeps them clinging together.
When a student finishes the laundry and takes his clothes out of the dryer, he discovers that his cotton sock is sticking to his wool sweater due to static electricity. Use the image above to explain.
How and why did the sock and sweater become electrically charged?
When the cotton sock and wool sweater tumbled together in the dryer, the friction between the fabrics caused electrons to transfer from one material to the other, resulting in the sock becoming positively charged and the sweater becoming negatively charged.
What is meant by conservation of charge?
Total electric charge in an isolated system never changes
Describe electron movement in terms of induction, conduction, and friction.
Induction refers to the redistribution of electrons within a neutral object due to the proximity of a charged object without direct contact.
Conduction involves the direct transfer of electrons between objects when they touch.
Friction describes the transfer of electrons between two materials when rubbed together.
Describe an experiment you could conduct to demonstrate static electricity.
Will vary.
