Angular acceleration is in units of inverse square seconds (because radians are dimensionless).
e.g. imagine a 3 kg mass on the end of a 5 metre arm, which has an angular acceleration of 0.5 inverse square seconds. The linear force is then 7.5 Newtons. mu'o mi'e ros 2009/12/11 Jorge Llambías <jjllamb...@gmail.com> > On Thu, Dec 10, 2009 at 7:15 PM, Pierre Abbat <p...@phma.optus.nu> wrote: > > On Thursday 10 December 2009 16:49:57 Jorge Llambías wrote: > > > >> Only it's actually 3.75 newtons. :) > > > > That depends on whether "2 seconds to the second power" means 2 square > seconds > > or the square of 2 seconds. > > You push a 3 kg object on a frictionless surface for 2 seconds with > both hands, exerting the same constant force with each hand.
