Study Notes

Natural Phenomena: Electricity

Lightning is a streak of light.
Charging by rubbing creates a charged object. An uncharged object does not have an electric charge.
Examples include rubbing a balloon on hair or wool to produce electrostatic force resulting in attraction or repulsion between objects.
There are two types of electric charge: positive (+) and negative (-).
Like charges repel each other.
Unlike charges attract each other.

Transfer of Charges

Electric charges can be transferred from one object to another through a metal conductor.
An electroscope detects the presence and quantity of electric charge.
Earthing is the transfer of charge to the Earth.

Lightning and Hunters

Lightning is a natural example of electrostatic force.
Lightning occurs when positive and negative charges move toward each other in the air.
