Physics 9 - Unit 1 (Static Charge)

Describe Static Electricity/How static charges form

Electric Charges that can be collected and held in once place, imbalance of number of protons: number of electrons on a surface material

How does friction make neutral objects charged?

Friction causes electrons to be transferred from one material to another, creating a charge imbalance (some materials lose electrons, some gain)

Conductors

Materials that allows electrons to easily move around (e.g metal, copper, aluminium)

Insulators

Materials that don’t allow electrons to move around easily (e.g wood, rubber, glass, plastic)

Triboelectric series
