PRESENTATION OUTLINE
OPPOSITES ATTRACT
- Attraction: strive for stability: particles w opposite charge attract
- Electrons are always moving seeking positive protons
- Looking for positive proton to be stable
- Move or travel: around always looking: ignore if all there
- Attractive force to become a stable atomm

STATIC ELECTRICITY
- Imbalance of positive and negative charge
- Excess of negative or excess if positive
- Static bc electrons are not miving there are built up
- Clouds pick up pos or neg charge from air or get striped
- Say it builds up neg charge

Untitled Slide
- CLoud w negative charge gets close to tree
- Its going to be attracted to positive charges while repelling neg charge
- Pushes down the negative charges and pulls up the positive charges
- Force becomes strong enough that the electrons jump from the cloud
- This is a lighting strike: electrons moving

STATIC SHOCK
- Shock you get when you become staticky charged
- And touch something metal
- You have a doorknob w no charge, walk to rubbing feet
- Feet are building up a negative charge building up electrons
- Colkects on body: Doorknob pushes away neg and strives pos: attracting

Untitled Slide
- If you touch that surface again you dont get another shock
- Touch charge becomes stable: match and beccome netural
- Conductors: Mive easily inside: pastic/ wooden no shock- insulators
- Metal w conduct and can easily move w in for static to jump

ELECTROMOTOR FORCE
- Battery and generator
- Battery: must have:
- Generator lights up battery
- Swuch direction of current
