Compute centripetal acceleration a = v²/r = ω²r.
Input Data
Speed
m/s
Radius
m
Results
a_c = v²/r.
20m/s²
At a glance:a_c = v²/r = ω²r (toward the center). Complements centripetal-force and banking-angle.
Formula
a_c = v² / r.
$$a = \dfrac{v^2}{r}$$How to Use
- Enter speed and radius.
- The tool returns acceleration.
Case Studies
v=10, r=20
a_c = 5 m/s².
FAQ
Direction?
Always toward the center of the circle.
