PPT-Interaction of Charged Objects

Attraction can happen also for likecharged objects Repulsion can happen only for likecharged objects Intervening matter does not block the E field The resulting field is a . Introduction to Electricity. Let review…. All matter is made up of atoms.. Atoms are made of charged subatomic particles.. Electric charge is a fundamental property of matter, similar to mass.. The electromagnetic force exists between protons and electrons. Like charges repel. Opposite charges attract.. Units of Chapter 16. Static Electricity; Electric Charge and Its Conservation.

What rooms in your house and school seem to produce the worst shocks from static electricity?. What can you do to minimize or eliminate the problem?. This effect occurs only when electric charges shift from their normal neutral position and is transferred from one object to another.. Prior Knowledge.
