Does the motion of second hand of a watch represents uniform velocity and uniform speed?

 \Huge{\boxed{\pink{\mathcal{ANSWER}}}}

Before moving on the answer for this question, we've to understand, "what is uniform velocity and uniform speed?"

 \Large{\bold{Uniform\:velocity\::\:-}}

A body is said to be in a uniform velocity if it covers equal distance with equal interval of time a particular direction.

For example : - A car is moving on a straight road with constant velocity.

 \Large{\bold{Uniform\:speed\::\:-}}

If a body covers equal distance in equal interval of time, then the body is said to be in uniform speed.

For example : - A vehicle moving on a straight road with constant speed.

Now we have to understand that, when uniform velocity and uniform speed come up with together.

 \large{\bold{When\:uniform\:velocity\:and\:uniform\:speed\:come\:together?}}

When an object is travelling on a straight line and moves with equal distance in equal interval of time, then the object is travelling both with uniform velocity and uniform speed.

For example : - When an object is travelling with a constant speed with equal interval of time on a straight road.

But, what's the difference between uniform velocity and uniform speed?

 \large{\bold{Difference\::\:-}}

The main difference between uniform velocity and uniform speed is that, when an object is travelling without changing it's speed, then the object is said to be in uniform speed and when a body is travelling without changing the speed but in a straight line then the object is said to be in uniform velocity.

Now, we can come up with our questions. Which is,

 \bold{Does\:the\:motion\:of\:second\:hand\:of\:the\:watch\:represents\:uniform\:velocity\:and\:uniform\:speed?}

No. The motion of second hand of the watch doesn't represents uniform velocity and uniform speed.

 \bold{Why?}

Because it is travelling in a circular path. Here, the direction of path is changing in every point. Here, it will represent the accelerated motion as it is travelling in a circular direction where the acceleration is changing at every point.

So, the second hand of the watch is neither representing uniform velocity nor uniform speed.

 \Huge{\boxed{\pink{Answer\:=\:No.}}}

But here arises a doubt. That is, "does the second hand of the watch represents uniform motion or accelerated motion?"

It travels in accelerated motion as it is travelling in a circular direction where the acceleration is changing at every point.


Overall, the answer for your question is,

Answer:

The seconds hand of the watch represents uniform motion. It moves with constant or uniform speed. It would have had a uniform or constant velocity if it travels in a specified direction in a straight line and moves over equal distance in equal intervals of time.
