Physics

When an object falls from rest, its motion follows a simple kinematic pattern with constant acceleration. The key insight is that you can rearrange the fundamental kinematic equation $s = \frac{1}{2}gt^2$ to isolate $g$, since you know the distance fallen and the time it took. This gives you a direct way to measure gravity's strength from everyday falling-object experiments.
