Time waits for none right! But how do you know that? The change in time is illustrated only by a watch or other measuring devices. A ticking watch measures the change in time but have you ever thought how it was measured before the invention of the watch? Let’s sneak peek into its measurement.
The basic unit of time is second. It is designated by the symbol ‘s’. The larger units of time are a minute (min) and Hours (hrs). These units are connected as follows:
1 hour = 60 minutes
1 minute = 60 seconds
The watches generally show seconds as the smallest unit. With the innovative technologies used in watches, today can measure units smaller than the second. These units are called millisecond and microsecond. These kinds of watches are used by sportsmen and athletes. While writing units we must always remember that a unit of any measurement is written in singular form.
From the simple phenomenon of repeating events to simple pendulums and the quartz watches, measuring time has come a long way. This shows that measuring it accurately, has been one of the prime concerns of human beings. The everchanging world of clocks and watches that intend to measure it beyond human imagination has given birth to a better technology of measuring the same.
Sample Questions For You
Q: What is the time taken by a pendulum to complete one oscillation called?
A) Amplitude B) Time Period C) Frequency D) Mean Position
Solution: A) As we discussed in the motion of a simple pendulum, the maximum displacement of the bob from its mean position is its amplitude.
