Centripetal Acceleration
The inward acceleration of an object moving in a circular path, directed toward the center of curvature.
Governing formula
ac = v² / r = ω² r
SI unit
m/s²
In depth
Centripetal acceleration alters velocity vector direction without changing scalar speed.
Examples in the real world
Passengers on a centrifuge ride experiencing high G-forces due to centripetal acceleration.
