Question

Describe how an electric charge is developed by friction or by contact.

Answer 1

Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.

Answer 2

Friction can buildup of electrical charges because let's say ur running a balloon on your hair it will cause static electricity. Therefore rubbing too things together causes friction then a buildup of electrical charges.

OR

Friction causes electrical buildup by making the electrons of the two things rub against each other creating heat. Happy to help :)
