Doubt in uniform circular motion

AI Thread Summary
In uniform circular motion, speed can remain constant while velocity changes due to the continuous change in direction. Velocity is a vector quantity, meaning it has both magnitude and direction, which is why it varies in circular motion despite constant speed. The discussion highlights that while the speed of a particle can be constant, the acceleration is non-zero, indicating a change in velocity. Additionally, the concept of helical motion is introduced, where a particle can maintain constant speed while its velocity changes due to the path's curvature. Understanding these principles is essential for grasping the dynamics of circular and helical motion.

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.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
