If talking about a particle rotating around an axis away from it by r. if the particle is moving with constant angular velocity ω. is the linear velocity constant or no?
Now what I know is that since we have Vt= ωr, so r doesn't change, as well as ω, so Vt is said to be constant. but I think it's not right to say that the linear velocity is constant since we have continuous changing in the direction of Vt, but I believe it's a constant linear speed. so, does this mean that at (linear acceleration) is available even when the magnitude of the linear velocity is not changing only the direction does? (since any change in the direction means we have an acceleration)?
when i come to at=α t, if we have an at, then this means we have α which must be zero. so my way of thinking is wrong! right?
this means that it is only for the changing of the magnitude of velocity, right? if yes then what is the linear acceleration that is resulted from the changing of vt direction?
