Summary of Electrostática (parte 1): Introducción a carga y la Ley de Coulomb

00:00:00 - 00:10:00

In this video, the concept of electric charge is introduced, along with Coulomb's law, which governs the force of attraction between particles with different charges. The formula for this force is provided, and an example calculation is shown.

• 00:00:00 In this video, I'm going to talk about one of the most mysterious forces in the universe- electromagnetism- and start by discussing electricity and its charge. I'll then go on to talk about the electrostatic property, which comes in two flavors- positive and negative. These two objects have a different charge, and as a result, they will repel each other. I'll call this repulsion charge charge "positive" or "negative." In reality, few people know exactly what electromagnetism is and what its fundamental properties are. However, as long as we recognize that it's a property, and that it comes in two variants, we'll be okay. I'll then talk about the fundamental unit of charge- the electron- and explain that it has a positive charge as well. Further down the line, I'll talk about particles that have both positive and negative charges, and I'll call these "electrons." Electrons are much smaller than protons and neutrons, and they have a property called spin.spin. This spin is what gives electrons their name- it's a bit like having two sets of hands. Just like with our regular hands, we can do things with our "inner hands
• 00:05:00 In this video, an introduction is given to electric charge and Coulomb's law. Electrons and understanding these things helps us understand a little more about what a butt is. In terms of fundamental units, a butt is equal to good. A colon is defined as the electric charge that we have in 6.24 units of 10 protons to the 18 negative charges or 6.24 units of 10 to the 18 fundamental units. Now, it is useful to put things reversed and say that a fundamental unit, or electric charge of a proton, is equal to 1.6. 1.6 units of 10 to the minus 19 butts are very well. Now, these numbers may at first seem arbitrary or you may ask why we would put 6.24 units of 10 to the 18 into fundamental units. And fundamental units here and well. After we discuss a little bit about electricity, we will grab some intuition by the way. Imagine what good numbers are like. Then, imagine what state an object is in. For example, if you were to ask me what the state of an object is, and I had to remember it, it would be good. However, most problems that give us one of these constants, or at least one, will require you
• 00:10:00 In this video, a formula for electricity is introduced, and the law of Coulomb is explained. This law states that the force of electrical attraction is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges. This equation can help us understand a little bit what happens with the universe, but, fortunately, we're going to return to this formula and see what it says basically. It says that the electric force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges. Now we can use this formula to calculate the force of attraction between particles. For this problem, I've given you the data for a charge of 5 units of charge positive towards a charge of 3 units of charge negative located at a distance of 0.5 meters. I've also given you the data for a charge of -10 units of charge positive towards a charge of -2 units of charge negative located at a distance of 0.5 meters. To calculate the force of attraction, we first use the law of Coulomb to determine the magnitude of the force of attraction. This calculation results in a force of 45 Newtons. Next, we divide this force by the distance between the charges,
