Physical Simulation
The use of computer programs and numerical algorithms to simulate the time-dependent physical behavior of real-world or theoretical systems.
Governing formula
x(t + Δt) = x(t) + v(t) Δt + ½ a(t) Δt²
SI unit
Computational Modeling
In depth
Replaces intractable hand calculations by discretizing continuous differential equations into finite time steps (Δt) and spatial meshes (Δx), enabling virtual experiments across astrophysics, aerodynamics, and climate science.
Examples in the real world
Simulating galaxy formation across cosmic time and aerodynamic airflow over aircraft wings.
