Study Notes
Electricity and Electrostatic Forces
- The word 'electricity' originates from the Greek word 'ēlektron', meaning amber, which exhibits electrostatic properties.
- Coulomb's Law describes the forces between electric charges.
- Electrostatic forces play a significant role at the nanoscale, where they are responsible for the structure and properties of materials.
- A common example of electrostatic phenomena is the attraction of lightweight particles, such as hair, to rubbed amber or a balloon.
- Amber was historically known to attract lightweight particles after rubbing, exhibiting electrostatic properties.
- The force that describes the interaction between electric charges is electrostatic force.
- Static cling is an example of an electrostatic phenomenon.
- In a hydrogen atom, protons and electrons make up the atom and exhibit a strong electrostatic force between them.
