Question

A particle is in uniform circular motion with speed
V. The change in magnitude of velocity when it
covers half of circular path is​

Answer 1

Answer:

magnitude of velocity doesnt change in circular motion only the direction xhanges

Answer 2

Answer:

No change in magnitude of velocity

Explanation:

When a particle is in uniform circular motion with speed V.

Uniform speed :It is defined as the value of speed which remain constant with  time .It does not vary with time

Speed is the absolute value of velocity and speed is a scalar quantity.Scalar quantity is that quantity  which have magnitude only and have no direction.

Velocity is defined as the displacement covered by the particle in time t .

$velocity=v=\frac{dv}{dt}$

Velocity is a vector quantity .Vector quantity is that quantity which have both magnitude and direction.

When a particle moves in circular motion and it covers half of circular path then no changes occur in magnitude of velocity  but its direction also changes .

Hence, there is no change in magnitude of velocity when it covers half of circular path.
