Traditional physics education often relies on imperative programming or manual calculus, which can obscure the underlying symmetries and laws of nature. This paper proposes a functional programming (FP) approach—specifically using Haskell—to model physical systems. By leveraging strong typing, immutability, and higher-order functions, students can map mathematical equations directly to executable code, fostering a deeper conceptual understanding of mechanics and field theory. 1. Introduction

This approach prevents "state leakage," where an accidental modification in one part of the program breaks the physical consistency of the simulation. 4. Advanced Concepts: Symmetry and Types Learn Physics with Functional Programming: A Ha...

Furthermore, higher-order functions allow for the abstraction of coordinate transformations. A single Lagrangian function can be passed into a generic Euler-Lagrange solver, allowing students to switch between Cartesian and Polar coordinates without rewriting the core physics logic. 5.

) is not a command to change a variable, but a function that transforms a state into an acceleration. and higher-order functions

In an imperative style, one might loop through time and update a y variable. In Haskell, we define the physics as a pure function:
