# Energy conservation

1. Mar 6, 2008

in non inertial frames , a pseudo force act on the bodies
but is the work done by this force is real??????????

if it is ,will the law of energy conservation hold in non inertial frames too , as everything is gaining velocity due to pseudo acceleration.

There is no universaly recognized criteria in physics to determine whether something is "real" nor is there a universaly recognized definition of that term. But in my opinion, yes, the work is real.
If the inertial forces in that frame are monogenic (i.e. derivable from a potential energy function) and are not explicit functions of time, then yes, energy is conserved in those frames. However this may not be the case for frames of reference for which the acceleration does not a constant value.
