# The Laws of Quantum Physics: The Schrödinger Equation

The Schrödinger equation is one of the most basic formulas of quantum physics. With the Schrödinger equation, you can solve for the wave functions of particles, and that allows you to say everything you can about the particle — where it is, what its momentum is, and so on.

In the following version of the Schrödinger equation, the first term represents the kinetic energy and the second term represents the potential energy:
