Distribution function (physics)

In physics, a distribution function describes how a quantity is distributed over a range of values or states. It is often used in various fields, including statistical mechanics, thermodynamics, and quantum mechanics, to describe the statistical properties of systems consisting of many particles. ### Key Contexts: 1. **Statistical Mechanics**: In statistical mechanics, the distribution function characterizes the probability of finding particles within certain states defined by parameters such as energy, momentum, or position.
