- Velocity is greatest at the lowest point (the equilibrium position) — all potential energy has become kinetic there.
- Velocity is 0 m/s at the two end points (the turning points / maximum angular displacement).
- The tangential acceleration is 0 m/s² at the lowest point (there the tangential component of the restoring force is zero).
(Note: the radial/centripetal acceleration is not zero there because the speed is maximal.)
- The magnitude of the acceleration is greatest at the end points (maximum displacement), where the restoring (tangential) force — and thus the tangential acceleration — is largest and points back toward equilibrium.
