Chrisleo13 said:When it is 10:00, the hour hand on an analog clock is 300 ahead of the minute hand. How many minutes elapse (to three significant digits) before the minute hand next points in the same direction as the hour hand?I seems really easy, but for some reason I am not getting the right answer.
Can I use rotational kinematics?
Rotational kinematics is the branch of physics that deals with the motion of objects as they rotate or spin around a fixed axis.
An analog clock uses rotational kinematics to measure and display time. The hands of the clock rotate around a fixed axis, with each rotation representing a specific unit of time (e.g. one hour).
The seconds, minutes, and hours hand on an analog clock are all connected to the same axis, but they rotate at different speeds. The seconds hand makes one full rotation every 60 seconds, the minutes hand makes one full rotation every 60 minutes, and the hours hand makes one full rotation every 12 hours.
An analog clock keeps accurate time by using a small motor and gears to control the rotation of the hands. The motor is connected to a power source, which provides a constant force to keep the hands moving at the correct speed.
Yes, rotational kinematics can be applied to any object that rotates or spins around a fixed axis, such as a spinning top, a merry-go-round, or a planet orbiting around the sun. It is a fundamental principle in understanding the motion of many natural and man-made systems.
