App description

Calculation formula:

Circumferential speed

\(v= \frac {2πr}{T}\)

Radius

\(r= \frac {vT}{2π}\)

Time period

\(T= \frac {2πr}{v}\)

r = radius of the arc, T = time period

Usage example

Select item to calculate: circumferential velocity (V).

Radius (R): 5m.

Time period (T): 7S.

Click "calculate" to output the result.

Circumferential velocity (V): 4.49.
