This resource explores fundamental concepts of electrostatics including charge types (insulators and conductors), electrostatic forces, and the principles of grounding. Students will engage in hands-on activities like creating gelatin stalagmites and observing the electrostatic charge on objects using an electroscope. We will also delve into Coulomb's Law to calculate electric forces between charged particles, including practical problems using Van de Graaff generators. Enhance your understanding of electricity and the impact of electrostatics in the physical world.
