Centripetal Force vs Mass

公式

## 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.

计算示例

A 2 kg ball on a 3 m string swings at 5 m/s.

  1. 01F_c = m * v² / r
  2. 02F_c = 2 * 25 / 3
  3. 03F_c = 50 / 3
  4. 04F_c = 16.667 N
