Grade 9 Science - Static Electricity Flashcards
Where are the Protons and neutrons located in an atom?
The nucleus
Where are the electrons located?
The orbitals
How are objects charged?
when electrons move from one abject to another
What’s static electricity?
It’s the built of charge that is on the surface of an object
What does Static mean?
The act of not moving
What is Static Electricity also known as?
Static Charge
What’s a negative charge?
It’s when an object has more electrons than protons
What’s a positive charge?
It’s when an object has more protons than electrons?
How can you create a charge?
Friction is the most common
What’s Friction?
A force that resists the movement of two surfaces in contact.
What is the charge of an object that hasn’t used friction?
The charge is Neutral
What are the two laws of Static Electricity?
- The law of Attraction
2. The law of Repulsion
What’s the law of Attraction?
Opposite Charges attract
What’s the law of Repulsion?
Particles of the same charge repel each other
What’s the ability of an object holding onto electrons called?
Electrons Affinity
How else can electrons be transferred?
Through conduction
What is conduction|?
The act of transferring electrons through contact
How is conduction done?
When electrons transfer from a charged object to a neutral object?
What is the act of conduction also known as?
Electric Discharge
How does lightning happen?
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.
What are 3 Storm Warnings?
- If you hear and see lighting at the same time it is right above you
- Keep safe in large buildings and vehicles
- Stay away form objects that conduct electricity
What’s Conductivity?
The ability of how much an object allows electrons to pass through them
What’s an Insulator?
The ability of an object being able to hold but not let electrons through them
What’s state can an object be to be able to be an insulator?
Solid, liquid, and/or gas
What are 4 examples of an insulator?
- Rubber
- Plastic
- Glass
- Pure Water
What are 3 examples of a conductor?
- Copper
- Aluminium
- mineral ed water
