Centrifugal acceleration - radians^2?

  • #1

Homework Statement



I'm working a problem concerning centrifugal acceleration and I've stumbled on something I don't quite understand:





Homework Equations



F=mrω2 where ω=rad/s

So the resulting units: kg * m*rad2/s2


The Attempt at a Solution



I would expect acceleration to be in unit ms-2


What's up with these radians? What do they mean?

Note that there is 'linear acceleration' (i.e. rate of change of linear volocity) in m/s^2
and 'angular acceleration' (i.e. rate of change of angular velocity) in mrad/s^2 but of course radian is not an S.I. unit.

'radian' is a measure for an angle.
For example pi radians is equivalent to 180 degrees.
