observe the clockwise end of the clock what about his moves and speed?
Answers
Answer:
A clock will most probably have three hands: hour's hand, minutes' hand and seconds hand. You can certainly observe that seconds hand move fastest.
The seconds hand of a clock completes one rotation in 1 minute i.e 60 seconds.
The seconds hand of a clock completes one rotation in 1 minute i.e 60 seconds.Angular speed=angle swept by the radius vector÷time taken
The seconds hand of a clock completes one rotation in 1 minute i.e 60 seconds.Angular speed=angle swept by the radius vector÷time takenAngle swept for one complete rotation is 2π radians
The seconds hand of a clock completes one rotation in 1 minute i.e 60 seconds.Angular speed=angle swept by the radius vector÷time takenAngle swept for one complete rotation is 2π radiansTherefore, 2π/60=π/30
The seconds hand of a clock completes one rotation in 1 minute i.e 60 seconds.Angular speed=angle swept by the radius vector÷time takenAngle swept for one complete rotation is 2π radiansTherefore, 2π/60=π/30 Answer: π/30 radians per second
Also, take note... Whatever that can be observed and inferred by oneself is first hand information.
