2 Static Electricity

Objectives

➜ ➜ Observe the separation of positive or negative charges when objects are
rubbed together and explain the transfer of electrons and forces between
charged objects.

➜ ➜ Explain how a potential difference is generated between two charged
objects and how this potential difference can become large enough to
cause a spark (including lightning as an example of discharge).

Vocabulary

• Balanced • Friction • Potential difference
• Conductor • Insulator • Shock

• Electric charge • Negatively charged • Spark
• Electron • Neutral • Static electricity

• Energy • Positively charged • Transfer
