Understanding Physics Centripetal Acceleration
How we calculate. Centripetal acceleration = speed² ÷ radius. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Physics Centripetal Acceleration case uses speed (v) 10 and radius (r) 5. Enter the same figures below to reproduce the worked path.
What is Physics Centripetal Acceleration?
Center-seeking acceleration in UCM. Distinct from linear acceleration (Δv/t) and from F = ma (use m·a_c for force).
- v = tangential speed
- r = path radius
- Toward center
The Formula
Worked Example
Common Use Cases
- Homework: circular motion
- Lab: whirling-mass checks
- Study: link to centripetal force
Pro Tips
- Square speed before dividing
- Radius not diameter
- Pair with F = ma
Limitations: Physics Centripetal Acceleration results are educational physics study aids—not engineering certification, lab accreditation, or safety advice. Use consistent SI (or clearly labeled) units and confirm formulas with your textbook or instructor.
FAQ
Same as linear acceleration?
No. Linear average acceleration is (v−u)/t. Centripetal a is v²/r for circular paths.
What if radius is 0?
Acceleration is undefined—enter positive radius.
