# Will A Pendulum Clock Work In Space

Since (in theory, at least) a pendulum of a certain length always takes the same amount of time to swing back and forth, the pendulum is what keeps the clock to time.

No, not a simple pendulum. A simple pendulum needs gravity to accelerate it on the downward and decelerate it on the upward. Here’s a video of astronaut Don Pettit explaining this concept and showing a way to make a pendulum work in space by introducing a substitute for gravity.

Pendulums on Earth require gravity to pull the swing back down after they swing upwards. Since there is no gravity in orbit, there is no force that pulls the pendulum down and make it swing back and forth.

## More Answers On Will A Pendulum Clock Work In Space

### Why Pendulum Clocks Are Not Suitable For Spaceships?

So to give you a clear answer, mechanical pendulum clocks do not work properly in space, due to two reasons. Firstly, the temperature in space is very low, about -270 degrees celsius. This results in the material of the pendulum to contract by a lot. If the clock is calibrated for showing time on Earth, then the readings will be off by a lot.

Yes, if you were truly in outer space, not in orbit with all gravitational forces negligible, a pendulum would NOT swing. Edit: Oh- also yes, on the moon it would swing slower. huh.. the guy above said it would not swing if you “were” in orbit.. but isn’t everything in orbit somewhat b/c of the universal gravitational law 0 mongrel

As you point out, one can’t use a pendulum clock in space because there is no constant gravitational force. However, there are many ways to keep time, a pendulum clock on Earth is only one of many. All you need is a steady oscillator and a method of counting the beats. One can use any regular time keeper, the most obvious is a quartz crystal watch.

### If a pendulum is taken to a high altitude, does it gain or lose … – Quora

Pendulum clocks rely on gravity to regulate at a constant rate. Gravity on our globe is not uniform… Moving a clock from sea level at a poll to sea level at the equator will encounter a change in gravity because the earth is not a true sphere and it also rotates. In addition there other motion changes related to the rotation of the earth.

### How do pendulum clocks work? – Explain that Stuff

May 16, 2021A summary of how clocks work. In summary, then, the key parts of a pendulum clock are: A dial and hands that indicate the time. A weight that stores (potential) energy and releases it to the clock mechanism as it falls, very gradually, over the course of a day (or several days, if you’re lucky). Winding the clock raises the weight back up …

### How to Fix a Pendulum Clock | Hunker

Reasons and Fixes for Tic-Toc Troubles If your clock keeps stopping, it could be the space it rests on. If you’ve recently moved your clock, you should check the foundation for levelness. A clock that leans to the left or right at the slightest angle will throw your pendulum into pandemonium or stop it in its daily tracks for tracking good time.

### Pendulum clock – Wikipedia

A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is a harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates.From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the …

### The secret of the synchronized pendulums – Physics World

Recently, we have reproduced a modern version of Huygens’ experiment (figure 2) using two “monumental” pendulum clocks that were designed and built by Relojes Centenario – a specialist clock-making firm in Zacatlán, Mexico. The pendulum in each clock consists of a 5 kg metal mass attached to the lower end of a wooden rod just under 1 m …

### What Is an Atomic Clock? | NASA

The vibrations of the crystal act like the pendulum of a grandfather clock, ticking off how much time has passed. To know the spacecraft’s position within a meter, navigators need clocks with precision time resolution — clocks that can measure billionths of a second. Navigators also need clocks that are extremely stable.

### Foucault Pendulum | Smithsonian Institution

When you set the pendulum swinging it will continue to swing in the same direction unless it is pushed or pulled in some other direction. (This is due to a basic law of nature called Newton’s First Law.) The earth, on the other hand, will rotate once every 24 hours underneath the pendulum.

### How clockwork works: An introduction to windup mechanisms

Mar 29, 2022Like an old-fashioned clock, a clockwork device is completely mechanical and has these essential parts: A key (or crown) you wind to add energy. A spiral spring to store the energy you add with the key. ( Pendulum clocks store energy with weights that rise and fall, but other clocks and windup wristwatches use springs instead.)

### How To Adjust A Pendulum Clock – Home and Garden Digest

The first type is obvious: there is either a threaded nut under the pendulum bob (weight) or a knurled wheel in the center of the bob. Adjust the bob up or down in small increments by turning the threaded nut, then run the clock for a week to determine its accuracy. Repeat as necessary until the clock keeps time.

### Pendulum Clocks – Keywound Pendulum Clocks and Quartz … – The Clock Depot

the top of the Pendulum Clock and travels toward the bottom over the course of a week to power the clock instead of a spring. The pendulum swinging back and forth dictates how fast or how slow the time is indicated on the dial. The longer the pendulum, the slower the clock will run and the shorter the length, the faster the clock will run.
