# Can a pendulum watch give correct time in an artificial satellite?

## Can a pendulum watch give correct time in an artificial satellite?

Since the time period of the pendulum depends on the gravity of Earth therefore the pendulum clock in the satellite will not give the correct time and so we can’t use a pendulum clock inside a satellite revolving around earth. Aakash EduTech Pvt. Ltd.

### What is the time period of a simple pendulum on an artificial satellite?

(i) time period becomes infinity. (ii) frequecny becomes infinity. (iii) both time period and frequency becomes infinity.

Can a pendulum watch gives correct time in an artificial satellite explain?

No, in an artifical satellite, the body is in weightlessness state, whereg=0. The time period of pendulum watch. It means, inside the satellite pendulum does not oscillate. Hence pendulum watch connot word in satellite.

Can a pendulum oscillate in an artificial satellite explain?

No a pendulum doesn’t vibrate in an artificial satellite as there is no gravity.

## Why a pendulum clock does not work during free fall or in an artificial satellite?

As the artificial satellite is orbiting the earth the net force acting on the satellite is zero hence the net acceleration acting on it is zero. Thus the body inside the satellite will experience no force of gravity i.e no acceleration due to gravity.

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

On taking the pendulum to the top of a mountain, g will decrease, therefore, T will increase. The pendulum will take more time to complete one vibration, i.e., it will lose time.

Why does the time period of a pendulum change when taken to the top of a mountain or deep in a mine?

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.

When a pendulum clock at sea level is taken to the top of a high mountain it will?

A pendulum when moved from sea level to top of a mountain then the acceleration due to gravity decreases. Since, time period is inversely proportional to square root of acceleration due to gravity, decrease in the gravity increases the time period.

## Does altitude affect a pendulum?

Correct answer: While changing the altitude of the pendulum will change the period, it will do it only slightly unless you take it miles above the earth’s crust. Furthermore, decreasing the altitude of the pendulum will increase the force due to gravity, which will resulut in a decreased period.

### What is the effect on time period of a simple pendulum with altitude?

Because the strength of Earth’s gravitational field is not uniform everywhere, a given pendulum swings faster, and thus has a shorter period, at low altitudes and at Earth’s poles than it does at high altitudes and at the Equator.

How is a pendulum clock affected if it is taken to the Pole?

Since the time period has reduced, the pendulum will undergo more number of oscillations than that of at the equator. As a result, the clock at the pole will show more time than the correct time at the equator. Therefore, we can say that when the pendulum is taken to a pole, it will gain time.
