Coulomb's law describes the electrostatic force between two charged particles. It states that the magnitude of this force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. Essentially, the closer two charged objects are and the larger their charges, the stronger the force between them.
Let's experience the discovery of the famous Coulomb's law in modern form in first person perspective and find out why Ampere won the race for SI unit instead of Coulomb!

Moving on to our unit on the Physics of Electricity, it's time to talk about charge. What is charge? Is there a positive and negative charge? What do those things mean? In this episode, Shini talks about electrostatic forces, electrical charge, Coulomb's law, and the force between charged particles.
As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating and a crucial part of physics. In this episode of Crash Course Physics, Shini chats about capacitors, conductors, electric field lines, and how objects with net charge generate electric fields.
So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, everyone! Today, Shini has the task of breaking down Electrical Potential Energy, Electric Potential, Voltage, Capacitors, Energy Storage, and Potential Energy... it's a lot!
We will cover capacitors in Year 13.
