Centripetal acceleration
What this topic asks you to be able to do
- understand that centripetal acceleration is produced by a force of unchanging magnitude that is always at right angles to the direction of motion
- understand that centripetal acceleration is what brings about circular motion at a steady angular speed
- recall and apply the relationships a = rω² and a = v²/r
- recall and apply the expressions F = mrω² and F = mv²/r
