Why does a pendulum clock run fast on cold winter days?
Answers

Time period of a pendulum is directly proportional to square root of the length of the
Pendulum.
i) In winter the length of the pendulum decreases and its time period decreases. So clock goes
fast.
ii) In summer the length of the Pendulum increases and its time period increases. So the clock
goes slow.
