Question

in uniform circular motion speed of an is
(a) uniform accelerated motion
(b) non uniform accelerated motion
c) circular motion
(d) none of these
​

Answer 1

Answer:

c) Circular motion  

Explanation:

acceleration cannot be defined in this case because acceleration depends on velocity and displacement. Here the direction of the object is continuously changing.

Answer 2

Answer:

The Direction of the Velocity Vector

Objects moving in uniform circular motion will have a constant speed. ... The magnitude of the velocity vector is the instantaneous speed of the object. The direction of the velocity vector is directed in the same direction that the object moves.
