In physics, what criteria should be satisfied by a good clock?

Question

Pls..nid ur answers..its for me physics class. thank you

Answer 1

It depends on the type of experiment we are performing with clock as one of the apparatus.

If we need to measure very small time intervals then the 'least count' of clock must be small enough to give a satisfactory result in experiment. Sometimes just an ordinary wall clock would do, and sometimes we need the very sophisticated 'nano clocks' depending on the experiment.

Clock should be accurate in its time, i.e. it should not slow down or get fast during the experiments.

It should be preferably a stop clock so that we can stop it to take readings conveniently.

Answer 2

Under mesurement as it is measuring time. Accurate measurment measured is measured by an atomic clock.

Answer 3

A good clock would be one that maintained it"s accuracy for the greatest duration.
