Question

explain with example, how an object can be changed by friction.​

Answer 1

Answer:

Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge. When a polythene rod is rubbed with a duster, the friction causes electrons to gain energy.

Answer 2

Answer:

Charging by friction

Explanation:

When insulating materials rub against each other, they may become electrically charged. Electrons, which are negatively charged, may be rubbed off’ one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.

Glass rubbed with silk and hard rubber rubbed with fur are two examples of materials that can develop a considerable charge when rubbed together.
