Sometimes, it is called a sweep hand, but the hands on a clock usually are called hour, minute, and second.
The second hand on a clock was invented by Swiss clockmaker Jost Burgi in the late 16th century. Burgi is also credited with developing the first mechanical timepiece with a second hand.
What do you mean with "motion of the entire second hand"? Please bear in mind that different parts of the hand move at different speeds. The closest thing to a "motion of the entire second hand" might be the motion of its center of mass. In this case, the answer is clearly "no". The center of mass is closer to the center than the tip, and moves slower.
The pace of the system clock measured by the number of ticks per second is called the clock speed. This refers to how many processing cycles the clock completes in one second. It is often measured in hertz (Hz).
The needle of a clock is referred to as a hand.

The angular velocity of the second hand of a clock is pi/30 radians per second.
its least count will be one second
put clock oil on the second hand.

add a second minute hand. If you could add a second minute hand to an analog clock, you would be able to increase the precision by allowing the time to be determined to the second.
