Circular Motion

This interactive simulator explores Circular Motion in Classical Mechanics. Object on a string with centripetal acceleration and force vectors. 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

In uniform circular motion the speed is constant but the velocity vector turns, so there is a centripetal acceleration toward the center of the circle: a = ω²r = v²/r. The net force required is F = ma, pointing in the same direction as the acceleration (inward). Tension, gravity, or normal force can provide this in real setups.

Key equations

v = ω r,   T = 2π/ω
a = ω²r = v²/r  (toward center)
F = m a  (centripetal force)
