Why does the balloon not stay stuck to the wall?

Front

Humidity (water) in the air strips charge away from balloon outside because it's polar

Back

Rules for Conductors

Front

Excess charge will always move to the outside

Back

Triboelectric series-Electron affinity

Front

Low affinity: (Positive Charge) air, human skin, rabbit fur, glass, wool, silk High Affinity (Negative Charge): Teflon, PVC, Cling film, Gold, platinum Brass, Silver

Back

Static Electricity Rule 2

Front

When an object becomes charges it is due to an exchange of Electrons

Back

Static Electricity Rules: 5

Front

Charged objects are attracted to NEUTRAL objects because neutral object still posses an equal number of protons and electrons

Back

Can you get struck by Lightning in a car or plane?

Front

NO! Charge will be pushed to the outside and go into the ground.

Back

Negative Charge:

Front

Balloon (polyethylene)

Back

Sub Atomic Particles: Proton

Front

Charge q = 1.6 x 10 ^-19 C Mass m = 1.67 x 10^-27 kg

Back

Static Electricity Rules: Rule 4

Front

Conservation of charge. NO charge can be created or destroyed, only transferred between objects

Back

Rules for Conductors 2

Front

Excess charge/electrons always wants to find a path into the earth where it can get as far away from each other as possible. It wants to be "grounded"

Back

Conductors

Front

Conductors: Materials that allow electrons electricity to easily flow through them. Electrons are loosely bound to their atoms

Back

Static Electricity Rule 1

Front

All objects are considered electrically neutral unless they have been charged. Electrically neutral objects have the same number of protons and electrons

Back

Thunder

Front

When a leader and streamer meet and the current flows, the air around the strike becomes extremely hot. So hot, it actually explodes because the heat causes the air to expand so rapidly. The explosion is followed by thunder

Back

Insulators

Front

Materials that do not allow electrons to freely flow. Electrons are tightly bound to their atoms

Back

Lightning

Front

Any time there is an electrical current, there is heat associated with the current. Enormous amount of heat in lightning strike, enormous amount of heat. Bolt of lightning is hotter than the surface of the sun. Heat is the cause of the brilliant white-blue flash

Back

Conductors (examples)

Front

Metals, Salt water, human body, Water is polar

Back

Can you get struck by lightning in a car or plane?

Front

NO! Charge will be pushed to the outside and go around into the ground. Feroday Cage (car body sends it around the car)

Back

Insulators (examples)

Front

Wood, Fur, Plastics, Pure Water

Back

Electron charge Positive Charge

Front

Bunny Fur

Back

Static Electricity Rule 3

Front

Protons can't move. They are 2000 times more massive than electrons also there's that nuclear fission thing

Back

Static Electricity Rule 6

Front

For materials such as plastics (insulators) extra charge on the object stays localized... It does not move

Back

Sub Atomic Particles: Neutrons

Front

Charge q = 0 (neutral) Mass = m = 1.67 x 10 ^-27 kg

Back

Static Electricity Rule 7

Front

Like charges repel (-/-) or (+/+) Unlike charges attract (+/-)

Back

Balloon Against Wall FBDs + Charge Diagrams

Front

Back

Electric Charge

Front

Build up of sub-atomic particles
