Circular Motion Calculator
From a radius and either a speed, period, frequency or RPM, computes the centripetal acceleration and force, angular velocity and period.

Notes
- Centripetal acceleration is v²/r, always pointing toward the centre; it changes direction, not speed.
- The force needed, mv²/r, is why a tighter turn or higher speed feels so much stronger.
