Section 1

Question 1

Describe how lightning is produced.

Answer 1

when excess negative charge discharges to regions of positive charge

Question 2

Explain why if charge cannot be created or destroyed, electrically neutral objects can become electrically charged.

Answer 2

Electrically neutral objects become charged when gain or lose electric charges.

Question 3

Predict what would happen if you touched the knob of a positively charged electroscope with another positively charged object.

Answer 3

leaves of electroscope remain apart.

Question 4

Humid air is a better electrical conductor than dry air. Explain why you’re more likely to receive a shock after walking across a carpet when the air is dry than when the air is humid.

Answer 4

electric charge remainson an object in dry air, which is an insulator. Humid air is a better conductor and allows electric charge to drain away into the air.

Question 5

The accumulation of excess electric charge on an object

Answer 5

Static electricity

Question 6

Charge can be transferred from object to object, but it cannot be created or destroyed

Answer 6

Law of conservation of charge

Question 7

A material in which electrons are able to move easily

Answer 7

Conduction

Question 8

A material in which electrons are not able to move easily

Answer 8

Insulator

Question 9

Process of transferring charge by touching or rubbing

Answer 9

Charging by contact

Question 10

Rearrangement of electrons on a neural object caused by a nearby charged object

Answer 10

Charging by induction

Question 11

Define static electricity.

Answer 11

accumulation of excess electric charge on an object.
