The concept of potential is fundamental in physics. In just a few words, an electric potential is an energy per unit charge. A gravitational potential is an energy per unit mass (mass is the charge of gravity). But what does this really mean?
In this video, we will answer that question by exploring the notion of potential in detail.
First, we will learn about gravitational potential, usually a concept that is more intuitive to most students. After this, we will use this understanding to learn about electric potentials.
We will conclude by discussing the concept of voltage, which is just a difference of electric potential.
