1. charge

1.1. positive

1.2. negative

2. electrostatic force

2.1. attraction (opposite charges)

2.2. repulsion (like charges)

3. causes of static electricity

3.1. friction

3.1.1. by rubbing insulators

3.2. induction

3.2.1. charging without direct contact

3.3. conduction

3.3.1. charging through direct contact

4. electric field a region where a charge experience a force

4.1. positive charge

4.1.1. the electric field radiates outward from the charge.

4.2. negative charge

4.2.1. the electric field points inward toward the charge.
