It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...

Understand why the electric force can be zero in electrostatics by exploring charge interactions, symmetry, and superposition. This video explains the physical intuition and mathematical reasoning ...
