Because the period is based on the length of the pendulum, an increase in temperature (such as that as occurs in summer) will make the material, normally metal, in the pendulum expand - which is why better clocks often had wooden pendulum rods. Since it is longer its period increases and makes the clock run slower than normal. Numerous inventions were developed to counteract this effect, most taking advantage of the properties of thermal expansion of various materials and how they are arranged in the pendulum.

Why does pendulum clock run faster in winter but slower in summers?

the pendulum clocks gets slow because in summer its length increases due to expansion of heat but in winter it doesnt happens.


What is the reason of pendulum clocks become slow in summer?

During the summer the pendulum which is generally made of metal, expands due to the rise in temperature. this causes the pendulum to move slower and hence the clock becomes slower.

Why do all clocks make use of some peiodic motion?

doctor.Galileo Galilee found that a pendulum of a given length takes always the same time to complete one oscillation .this observation led to the development of pendulum clocks .winding clocks & wristwatch's were refinements of the pendulum clocks

Why does the pendulum clock run slower in the summer and faster in the winter?

The time period of a pendulum clock is given by T = 2 π root over l/g , where l is the length of the pendulum . Thus , T is directly proportional to lenght . in summers , T increases as l increases. while in winter , T will decrease as l decreases . Like wise , pendulum clocks go fast in winter and slow in summer

Was the digital clock invented after the pendulum clock?

Oh yes. pendulum Clocks rely on mechanics. Digital Clocks rely on Electronics. And we didn't learn to use Electronics until way later than mechanics.


What instruments did the Elizabethans use to tell the time?

They had pendulum clocks. (What you might call a grandfather clock). Also sundials, water clocks, candles.
