Question

Observe the second hand of clock and tell about its speed and velocity

Answer 1

Answer:

yes

really

you don't know this oh know

Answer 2

The second hand of a clock rotates along an axis. Its centre is fixed. Many people get confused with this. The motion of entire second hand of a clock is rotational motion, while the motion of each point on the second hand is circular motion, except the point at which the second hand is attached to the clock. That point is stationary.

Therefore, the velocity is changing as direction is changing at every point while the speed remains constant.
