Magnus Effect (Ball)

This interactive simulator explores Magnus Effect (Ball) in Classical Mechanics. Same v₀ and θ with vs without spin: toy a = (kωv_y, −g − kωv_x); range comparison. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Classical Mechanics.

How it works

A **spinning** ball moving through air feels a **sideways** lift force (**Magnus**), crudely **F ∝ ω × v** in direction. This is a **2D particle** demo with a **tunable** coupling **k** — not a Navier–Stokes solve. **Gray** trace: same initial speed and angle **without** Magnus; **cyan**: with **ω** and **k**. Change **ω** sign to bend **left vs right**.

Key equations

a_x = kωv_y · a_y = −g − kωv_x — schematic only
