Question

Why is quartz clock more accurate than pendulum clock?

Answer 1

In a pendulum clock their can be difference in the readings due to the temp variation

As the temp increases, the length increases and hence the time period increases

T = 2π√(l/g) ======> T directly proportional to length

l = l(1+α∆t) =======> l directly proportional to t(temp)

In a quartz clock the vibrations of the quartz is used to measure the time which does not change with change in temp
