Centripetal Acceleration
Calculate circular motion forces using Linear Speed (v) or Angular Velocity (ω).
Physics Formula
ac = v² / r
What is Centripetal Acceleration?
Centripetal acceleration is the rate of change of tangential velocity of an object moving in a circular path. It is always directed towards the center of the circle.
Angular Formula
Used when you know the rotation rate (ω) in units like RPM or rad/s.
ac = ω² · r
Centripetal Accel Calculator Guide
Centripetal Acceleration
Centripetal acceleration keeps an object moving along a circular path by continuously changing its velocity direction.
Formulas
- a_c = v² / r
- a_c = ω² r
Example
For v=12 m/s and r=8 m: a_c = 144 / 8 = 18 m/s².
FAQs
Direction?
Always toward the center of the circular path.
Uniform circular motion?
Speed constant, direction changes; acceleration is non-zero.
