Electric Forces

Electric Forces

The SHOCKING truth

Electric Forces

• Force generated from charged atoms (+ or -)

• Like charges repel; opposite charged attract

• Electric force increases when

  • charge increases

  • charges are closer together

Charged Objects

• Objects can gain or lose charges particles

• Electrically Charged - unbalanced amount of + and - charges

• Electrically Neutral - equal amount of + and - charges

  • do not attract or repel each other

  • can be attracted to charged objects

Conductors vs Insulators

• materials where charges cannot move easily

• glass, rubber, wood

• prevent flow of electricity

Insulators

• materials where charges can move easily

• copper, aluminum

​Conductors

Conduction vs Induction

• charging an object without touching it

• charging a cell phone

Induction

• transferring of charges from one conductor to another by touching

• negative charges will move to the object with less negative charges

​Conduction

Moving Charges

• Electric Current - movement of electrically charged particles

• Circuits - made from an electric energy source, conductor and electric device

  • Closed Circuit - complete pathway for electricity

  • Open Circuit - incomplete pathway
