So I was thinking, I never heard about gravitational potential, yet there is such a big deal about electrical potential. Why is it so much more important that voltage be taught, yet no mention of its gravitational analog?

Electrical potential is important in physics because it is a fundamental quantity that helps us understand the behavior of charged particles in electric fields. It allows us to calculate and predict the movement and interactions of these particles, which is crucial in understanding many natural phenomena and developing new technologies.
Electrical potential and electrical charge are two different quantities that are closely related. Electrical charge refers to the amount of electric charge that a particle carries, while electrical potential is a measure of the potential energy that a charged particle has due to its position in an electric field. In other words, electrical potential is a measure of how much work would be needed to move a charged particle from one point to another in an electric field.
Electrical potential and voltage are often used interchangeably, but they are not exactly the same. Voltage is a measure of the difference in electrical potential between two points in an electric field. It is often described as the "push" or "force" that moves charged particles through a circuit. So, while electrical potential is a scalar quantity, voltage is a vector quantity that takes into account both the magnitude and direction of the electric potential difference between two points.
Electrical potential is calculated using the formula V = kQ/r, where V represents the electric potential, k is a constant, Q is the charge of the particle, and r is the distance between the particle and the point at which the potential is being calculated. This formula is known as Coulomb's law and is an important equation in electromagnetism.
Understanding electrical potential is crucial in many real-world applications, such as in the design and operation of electronic devices like computers, cell phones, and televisions. It is also important in power generation and transmission, as electrical potential is what drives the flow of electricity through power lines. Additionally, understanding electrical potential is essential in the study of lightning and other atmospheric electrical phenomena, as well as in the field of medical imaging techniques like electrocardiograms and electroencephalograms.
