Answer 4

It’s the built of charge that is on the surface of an object

Question 5

What does Static mean?

Answer 5

The act of not moving

Question 6

What is Static Electricity also known as?

Answer 6

Static Charge

Question 7

What’s a negative charge?

Answer 7

It’s when an object has more electrons than protons

Question 8

What’s a positive charge?

Answer 8

It’s when an object has more protons than electrons?

Question 9

How can you create a charge?

Answer 9

Friction is the most common

Question 10

What’s Friction?

Answer 10

A force that resists the movement of two surfaces in contact.

Question 11

What is the charge of an object that hasn’t used friction?

Answer 11

The charge is Neutral

Question 12

What are the two laws of Static Electricity?

Answer 12

1. The law of Attraction

2. The law of Repulsion

Question 13

What’s the law of Attraction?

Answer 13

Opposite Charges attract

Question 14

What’s the law of Repulsion?

Answer 14

Particles of the same charge repel each other

Question 15

What’s the ability of an object holding onto electrons called?

Answer 15

Electrons Affinity

Question 16

How else can electrons be transferred?

Answer 16

Through conduction

Question 17

What is conduction|?

Answer 17

The act of transferring electrons through contact

Question 18

How is conduction done?

Answer 18

When electrons transfer from a charged object to a neutral object?

Question 19

What is the act of conduction also known as?

Answer 19

Electric Discharge

Question 20

How does lightning happen?

Answer 20

Electron s build up in the storm clouds. Once the electrons build up enough to create an electrical current to the nearest neutral/positive object.

Question 21

What are 3 Storm Warnings?

Answer 21

1. If you hear and see lighting at the same time it is right above you
2. Keep safe in large buildings and vehicles
3. Stay away form objects that conduct electricity

Question 22

What’s Conductivity?

Answer 22

The ability of how much an object allows electrons to pass through them

Question 23

What’s an Insulator?

Answer 23

The ability of an object being able to hold but not let electrons through them

Question 24
