Question

Answer the question:-

1.What is time ?

2. Why is it necessary to have standard units of measurement?​

Answer 1

Answer:

1) Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. 

Time in physics is operationally defined as "what a clock reads".

2) We need standard unit for measurement to make our judgement more reliable and accurate. For proper dealing, measurement should be same for everybody. Thus there should be uniformity in measurement. For the sake of uniformity we need a common set of units of measurement, which are called standard units.
