Hi all,

Just a quick question about what practical uses knowledge of the angular momentum of a system has? For example, in an aircraft system, what would the angular momentum vector be utilised for? It seems like a kind of quasi-theoretical term that has minimal purpose, but I doubt this is the case in real-world use. If the angular momentum is known, can this then be used to calculate external forces on the system which affect rotation, for example?

Thanks!

I guess, looking at the linear momentum equivalent, then the angular momentum is a measure of whether the object will continue rotating when an external force is applied to the object? Is this effectively what angular momentum represents?
