What happens when two objects made out of different materials are

rubbed together?

Subject: Electricity

Transfer of charges (electrons) from one body to another

Explanation:

When two bodies of different materials are rubbed together, this causes transfer of charges e - between the two bodies. The body that loses electrons becomes positively charged while the body that gains electrons becomes negatively charged.

When two objects of different materials are rubbed together, electrons transfer from one object to another. One object will become positively charged and the other, opposite. (Negatively charged) The positively charged one loses the electrons and the negatively charged one gains electrons.
