Here's why:
* Friction and Electron Transfer: When two materials rub against each other, friction causes electrons to be transferred from one material to the other.
* Imbalance of Charge: The material that loses electrons becomes positively charged, while the material that gains electrons becomes negatively charged.
* Static Electricity: This separation of charge, resulting from friction, is known as static electricity.
Examples:
* Rubbing a balloon on your hair: Electrons transfer from your hair to the balloon, leaving your hair positively charged and the balloon negatively charged.
* Walking across a carpet: Electrons transfer from the carpet to your shoes, making your shoes negatively charged and the carpet positively charged.
