Frequently Asked Questions
What is centripetal acceleration?
Centripetal acceleration is the acceleration directed toward the center of a circular path that keeps an object moving in a circle. It's always perpendicular to the velocity vector and points toward the center of the circular motion. The magnitude is calculated using formulas like a = v²/r or a = ω²r, depending on your known variables.
How do I calculate centripetal acceleration?
You can calculate centripetal acceleration using three main methods: (1) Linear velocity method: a = v²/r, where v is linear velocity and r is radius. (2) Angular velocity method: a = ω²r, where ω is angular velocity. (3) Period/frequency method: a = 4π²r/T² for period T, or a = 4π²rf² for frequency f. Choose the method based on your available data.
What units are supported in this calculator?
Our calculator supports comprehensive unit conversions including: Acceleration (m/s², ft/s², g-force), Velocity (m/s, km/h, mph, ft/s), Angular velocity (rad/s, rpm, deg/s), Distance (m, km, ft, in), Time (s, min), Frequency (Hz), and Mass (kg, g, lb, ton). All conversions are handled automatically for accurate results.

What's the difference between centripetal and centrifugal acceleration?
Centripetal acceleration is the real acceleration directed toward the center of circular motion that keeps objects in their circular path. Centrifugal acceleration is a fictitious acceleration experienced in rotating reference frames, appearing to push objects outward. Our calculator computes the real centripetal acceleration.
