Centripetal Force vs Mass
Centripetal Force
An object in circular motion requires a net inward force directed toward the center of the circle.
Formula
F_c = m * v² / r
This force does not do work since it is always perpendicular to velocity.
Example Calculation
A 2 kg ball on a 3 m string swings at 5 m/s.
- 01F_c = m * v² / r
- 02F_c = 2 * 25 / 3
- 03F_c = 50 / 3
- 04F_c = 16.667 N
