10: Rotational Mechanics
- #2Consider the following two equations
(A)
L=I ω(B)
dLdt=ΓIn noninertial frames
(a) both A and B are true
(b) A is true but B is false
(c) B is true but A is false
(d) both A and B are false.digAnsr: b,BAns : (b) A is true but B is false.
In non-inertial frames, `` \frac{dL}{dt}={\Gamma }_{\,\mathrm{\,total\,}}``
Here, `` {\Gamma }_{\,\mathrm{\,total\,}}`` is is the total torque on the system due to all the external forces acting on the system. So, equation (B) is not true as in non-inertial frames, pseudo force must be applied to study the motion of the object.
