# What effect would the temperature have on the time kept by a pendulum clock?

Contents

## How does temperature affect time period of pendulum?

When the temperature increases the length of the pendulum also increases and hence its time period increases. Thus it losses the time when temperature is increased.

## When the temperature of a pendulum is increased then the time period?

Increases as its effective length increases even through its centre of mass still remains at the centre of the bob. decreases as its effective length increases even though its centre of mass still remains at the centre of thed bob.

## Does temperature affect a grandfather clock?

Grandfather clocks are prone to thermal expansion and contraction of the pendulum rod, which changes in ambient temperature and humidity. So, to keep your clock on the most accurate time, you need to have a controlled temperature environment in your home.

## Why do pendulum clocks run slow in summer?

Pendulum clocks become slow in summer because the length of the pendulum increases due to which the time period increases and the pendulum takes more time to complete one oscillation. Thus it becomes slow in summer.

## What is the time period of a simple pendulum?

A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.

## How the period of oscillation of the pendulum of a clock may be affected by an increase in temperature?

An increase in temperature causes the rod to expand, making the pendulum longer, so its period increases and the clock loses time.

## Does temperature affect time period?

When the temperature increases the length of the pendulum also increases and hence its time period increases. Thus it losses the time when temperature is increased.

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

It is because the time period of a pendulum clock is directly proportional to square root of the length of the pendulam so it justifies the reason as: In winter the length of the pendulum decreases and its time period decreases. So clock goes fast. goes slow.

## What are the conditions for SHM?

Define simple harmonic motion. What are the conditions of SHM?

• There must be an elastic restoring force acting on the system.
• The system must have inertia.
• The acceleration of the system should be directly proportional to its displacement and is always directed to mean position.

## How long will a grandfather clock last?

Most quality new grandfather clocks will run about 20+ year if you set one up and never maintain it, but oiling every few years may make the clock last a lifetime (or two).

## Why pendulum clocks are affected by the temperature and pressure of air?

Temperature The most pronounced effect on the clock’s rate was caused by temperature change. … As cold air is denser, it adds more drag to the pendulum and the pendulum uses up more energy, reducing the arc of swing and so causes the clock to run slightly faster.

## How long does a grandfather clock go without winding?

Almost all grandfather clocks are made to run for seven or eight days without winding, so winding them on the same day each week will ensure that it never stops. If your clock stops before its regular winding time, however, you may need to wind it more frequently.
