# Why would a pendulum clock not keep correct time when on the moon?

## Would a pendulum clock work on the moon?

When the pendulum is taken to the moon, the value of ‘g’ will decrease and hence time period will increase. … As the pendulum takes more time to complete one vibration, it will lose time.

## Are pendulum clock that keeps correct time on the earth is taken to moon it will then run?

If the length of the pendulum is constant, this means, we are avoiding the thermal expansion, then time period is inversely proportional to the acceleration due to the gravity. This means, Pendulum clock on the moon will be √6 times slower on the moon.

## Will a pendulum clock gain or lose time when taken to the top of a mountain?

When the pendulum is taken to the top of mountain, the value of ‘g’ will decrease and hence time period will increase. As the pendulum takes more time to complete one vibration, it will lose time.

## Why doesn’t mass affect a pendulum?

The mass of a pendulum’s bob does not affect the period. … As mass increases, so does the force on the pendulum, but acceleration remains the same. (It is due to the effect of gravity.) Because acceleration remains the same, so does the time over which the acceleration occurs.

## What affects the swing rate of a pendulum?

The forces of gravity, the mass of the pendulum, length of the arm, friction and air resistance all affect the swing rate.

## What happens to time period when length is doubled?

Time period is directly proportional to the length…. So if length is doubled the time period is doubled.

## Can a pendulum swing in a vacuum?

In a vacuum with zero air resistance, such a pendulum will continue to oscillate indefinitely with a constant amplitude. However, the amplitude of a simple pendulum oscillating in air continuously decreases as its mechanical energy is gradually lost due to air resistance.
