Doubt in uniform circular motion

Click For Summary
SUMMARY

In uniform circular motion, the speed of a particle remains constant while its velocity changes due to the continuous alteration of direction. Velocity is defined as a vector quantity, which inherently includes direction; thus, even with constant speed, the velocity is not constant. The discussion also touches on helical motion, where a particle can maintain constant speed while experiencing changing velocity due to its path. This principle is applicable in various fields, including physics and engineering, particularly in the study of electron beams.

why are we considering speed is constant to find velocity a particle in uniform circular motion, is it possible for a particle in a circular motion to have constant velocity?

That doesn't make much sense, doesn't it?

BY DEFINITION, velocity is a vector, and circular motion involves something moving in a circle, i.e. CHANGING its direction all the time.

Zz.
 
The velocity in circular motion is necessarily everchanging, the speed need not be, and might well remain constant.

STOP SHOUTING !,! Makes my eyes ache. :)
Motion in a helical path might interest you, this could be a combination of circular motion...where you have constant speed but changing velocity because of the changing direction. You could also have the circle moving at constant velocity to trace out the helix. This sort of 'circular' motion is common with electron beams.
 
by use of natural coordinates, it is very easy to prove that with constant speed and a fixed non-zero acceleration, the particle's motion must be circle. Moreover, if the particle's acceleration is zero, its trajectory is a straight line. I am a college teacher, believe in me.
