Centripetal force
Fill in any fields — the empty ones are calculated, so it works in every direction.
Formula
F = mv²/r
Worked example
Given: Mass = 1,000 kg; Speed = 60 km/h; Radius = 50 m
Result: Force = 5,555.56 N; Acceleration = 0.5665 g
How it is calculated
1. Enter the values you know. 2. The calculator converts them to base units and applies the formula. 3. The result is shown in the unit you choose.
