I am right now studying Rigid Body dynamics..
I have some doubts regarding Dynamics...
1) When a body is rotating as well as translating...we say that every particle of the ..lets say ROD is moving with a resultant velocity = Vcm ( translational velocity of COM) + ω.R (where R is the distance from COM ) ( ω is angular velocity..)
My doubt is that how do we knw that every particle of the rod is translating with a velocity with which the COM is Translating...
2) My sir told that ω of a body is same whatever be the axis of rotation ..
And that's why we very effectively use the Angular Momentum conservation theorem ..
