How It Works

Centripetal Acceleration

An object moving in a circle at constant speed still accelerates because its direction changes.

Formula

a_c = v² / r

This acceleration always points toward the center of the circular path.

Worked Example

A car travels at 10 m/s around a curve of radius 5 m.

velocity = 10radius = 5
  1. 01a_c = v² / r
  2. 02a_c = 100 / 5
  3. 03a_c = 20 m/s²
