Back

By rubbing two different materials together, such as feet on a carpet.

Front

What is the relationship between electric charge and attraction?

Back

Opposite charges attract each other, while like charges repel.

Front

What happens when a negatively charged object touches a neutral object?

Back

Electrons can transfer from the negatively charged object to the neutral object, giving it a negative charge.
