The long hand
It is the long hand.
the second hand
The minute hand is the largest hand on most analogue clocks. At 3 o'clock on a 12-hour clock, the minute hand is pointing straight up to the 12. It measures time to the nearest minute by advancing one of the small minute hash marks every 60 seconds. Every time the second hand makes one full sweep of the clock face, the minute hand advances one of the minute marks. The second hand is the fastest moving hand on a standard analogue clock, making one full sweep every 60 seconds.

so you can tell them apart
Yes, the Big Hand on a clock is typically the Hour Hand. It indicates the current hour on the clock face, while the Little Hand, or Minute Hand, indicates the minutes.

the second hand
The time period of a nimute hand on the clock is one minute since it takes a minute for it to complete one oscillation, ie., one complete cycle of the clock.
The minute hand of a clock turns about 360 degrees each hour.
The minute hand is the largest hand on most analogue clocks. At 3 o'clock on a 12-hour clock, the minute hand is pointing straight up to the 12. It measures time to the nearest minute by advancing one of the small minute hash marks every 60 seconds. Every time the second hand makes one full sweep of the clock face, the minute hand advances one of the minute marks. The second hand is the fastest moving hand on a standard analogue clock, making one full sweep every 60 seconds.
The long hand is called the minute hand, the shorter fat one is called the hour hand. Based on historical design the BIG hand is the hour hand because an hour is bigger than a minute. Function first, then form. Traditionally clocks had fatter hands for hour and thinner hands for minute, thus BIG is hour and LITTLE is minute. Yes the minute hand is usually longer than the hour hand but on most clocks the hour hand is larger not just shorter. Don't confuse long, big, little, and short.
Hour hand and minute hand.
Whoever invented the clock.
A clock's second hand makes one complete revolution each minute. Thus, by definition, it is rotating at one revolution per minute or one RPM. That's its "rotational velocity" and it is the same no matter how big or small the clock might be. The actual velocity that the tip of the second hand might trace out as it revolves around the center of the clock will vary with the length of the second hand. The longer the hand, the faster the tip moves around the circumference.
