Free Fall
This interactive simulator explores Free Fall in Classical Mechanics. Drop objects of different masses with optional air resistance. Prove Galileo right. 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: Suited to beginners and first exposure to the topic. Typical context: Classical Mechanics.

How it works
In vacuum, all objects fall with the same acceleration g regardless of mass — Galileo’s famous result. With linear air resistance, acceleration decreases as speed grows until terminal velocity is approached. Without drag, each timestep uses exact constant-g kinematics (no Euler drift in y, v). With drag, motion is integrated numerically. Height is above ground with downward-positive velocity.
