Lesson: Static Electricity Physics • 9th Grade

Students will be able to

• recall that there are two types of electric charges: positive and negative,
• recall that opposite electric charges attract each other,
• recall that like electric charges repel each other,
• recall that the attractive or repulsive force between charges is greater if the charged objects of particles are closer together,
• recall that the attractive or repulsive force between charges is greater if the magnitude of the charge is greater,
• interpret graphs of force against the distance between charged objects or particles,
• recall that electrons have a negative charge,
• recall that protons have a positive charge,
• recall that neutrons have no charge,
• recall that electrons can be transferred between materials to create a buildup of charge, known as the static electricity,
• recall that acetate and polythene rods can be given static charges by rubbing them with cloths.
