Centripetal Acceleration Calculator
Calculate centripetal acceleration from speed and radius.
Enter values to calculate.
Centripetal Acceleration Formula
a = v²/r.
Practical Example
Use a simple set of known values and calculate the result. Compare the magnitude with an expected reference, then change one variable to observe how the physical relationship responds.
Factors That Affect the Result
Input precision, unit consistency, direction conventions, constants and idealized assumptions affect the result. Real systems may include additional forces, losses or environmental effects not represented by the basic equation.
Frequently Asked Questions
Do direction and sign conventions matter?
Yes. Vector quantities and angular values can depend on the chosen convention.
Can rounding affect the answer?
Yes. Intermediate and final rounding can produce small differences.
Should I compare the result with a reference?
Yes. A known example is useful for checking units and scale.
