What is the difference between centre of gravity and centre of mass? There is one, although it would make no difference in this context.

I am bored with center of mass

That is a serious affection !

A remedy might be to spend a bit more time on R & R , socialize and such.

In extreme cases of brilliance, stepping up from center of mass to e.g. tensor of moment of inertia can be diverting

As haru says: ain't no difference, so a definite 'Yes'

I think center of gravity changes but not center of mass. I think we can balance things by center of gravity not with center of mass.

center of gravity changes

Under what circumstances?

Under what circumstances?

Near black holes etc. Where we balance things with center of gravity and also where center of mass is completely useless. Shuttlecock flips with center of gravity not with center of mass.

Shuttlecock flips with center of gravity not with center of mass.

No.

Have you ever played badminton on the moon?

Have you ever played badminton on the moon?

No. Please explain why did you ask me such question?

 

[jbriggs444]

No. Please explain why did you ask me such question?

To suggest that gravity is not the only factor affecting a shuttlecock.

Shuttlecock flips with center of gravity not with center of mass.

I don't understand what you are saying here. Please explain in detail. In particular, please explain what you think the difference is between the two centres.
