The velocity of any point P of a rigid body in rotation plus translation is [itex]\vec{}v[/itex]

Now |[itex]\vec{}v[/itex]

But v and rω are same thing as v=rω ,so velocity of the particle every time will be √2 v.Then what is the difference between [itex]\vec{}v[/itex]

_{p}=[itex]\vec{}v[/itex]_{COM}+[itex]\vec{}v[/itex]_{p,COM}.Now |[itex]\vec{}v[/itex]

_{COM}|=v and [itex]\vec{}v[/itex]_{p,COM}=rω .But v and rω are same thing as v=rω ,so velocity of the particle every time will be √2 v.Then what is the difference between [itex]\vec{}v[/itex]

_{COM}and [itex]\vec{}v[/itex]_{p,COM}?#### Attachments
