A pendulum clock keeping correct time is taken to high altitudes, (a) it will keep correct time ← Prev QuestionNext Question → 0votes 13.1kviews askedApr 30, 2018in Physicsby paayal(147kpoints) A pendulum clock keeping correct time is taken to high altitudes, (a) it will keep correct time (b) its length should be increased to keep correct time

Acceleration due to gravity only changes as we move at high altitudes and it decreases. since, g decreases, this means Time Increases. Now, Time Increment can be controlled only if length of the pendulum is decreased.

What happens to the time when the length of pendulum decreases?

since, g decreases, this means Time Increases. Now, Time Increment can be controlled only if length of the pendulum is decreased. If length is decreased, then ratio l/g is constant and hence the watch will give the correct time. Hence, Option (c). is correct.

What happens to a simple pendulum when taken from equator to Poles?

It will run about 0.25% slower, because the Gravity of Earth increases by about 0.5% from equator to pole, and the frequency of a Pendulum goes up by the square root of the gravity. What happens to the time period of a simple pendulum when it is taken from equator to poles?

How can I control the time increment in a pendulum watch?

Acceleration due to gravity only changes as we move at high altitudes and it decreases. since, g decreases, this means Time Increases. Now, Time Increment can be controlled only if length of the pendulum is decreased. If length is decreased, then ratio l/g is constant and hence the watch will give the correct time.

How often should a pendulum oscillate on a grandfather clock?

A pendulum on a grandfather clock is supposed to oscillate one every 2.00s but actually oscillates once every 1.99s. How much must you increase its length to correct its period to 2.00s?

Pendulum clock (and time glass) are not relativistic instruments they simply lose time. Above 40 km from earth the acceleration due to gravity will be reduced by approximately 1 percent as ‘g’ varies inversly with square of distance. The time period of simple pendulum varies inversely to the square root of ‘g’ , hence, it will increase.

The period of a pendulum increases slightly with the width (amplitude) of its swing. The rate of error increases with amplitude, so when limited to small swings of a few degrees the pendulum is nearly isochronous; its period is independent of changes in amplitude. Therefore, the swing of the pendulum in clocks is limited to 2° to 4°.

What does the time period of a simple pendulum depend on?

The time period of the simple pendulum depends upon its length and gravitational acceleration. It is equal to twice the square root of length divided by gravity. For a physical system, the time period depends on its amplitude, length, and mass. It equals twice the square root of length divided by twice the square root of amplitude.

What happens to the pendulum clock in hilly areas?

When the value of g decreases, the value of T increases with the decrease in the value of g by taking the pendulum in hilly areas. However, the pendulum clock slows down. Case 5: With the rise in temperature of the pendulum, the effective length of a pendulum increases, along with the period. % increase in time period = 50 αӨ.

What is the use of a pendulum in music?

The pendulum is also used for identifying the beats. It is interesting to note that the time period of the pendulum remains constant even if the amplitude is changed but if the acceleration due to gravity changes the time period of the simple pendulum also changes.

How did the pendulum increase the accuracy of the first clock?

The introduction of the pendulum, the first harmonic oscillator used in timekeeping, increased the accuracy of clocks enormously, from about 15 minutes per day to 15 seconds per day leading to their rapid spread as existing ‘ verge and foliot ‘ clocks were retrofitted with pendulums. A lantern clock that has been converted to use a pendulum.

In 1907 his General Theory of Relativity showed that clocks run more quickly at higher altitudes because they experience a weaker gravitational force than clocks on the surface of the Earth. The phenomenon – called gravitational time dilation – has been demonstrated by putting atomic clocks on jumbo jets and flying them at high altitudes.

Einstein’s work famously showed that time is relative. In 1907 his General Theory of Relativity showed that clocks run more quickly at higher altitudes because they experience a weaker gravitational force than clocks on the surface of the Earth.

Why do clocks run faster at the top of the Earth?

The general relativity effect is because the clocks are higher in the Earth’s gravity filed and GR says time (not just physical clocks) runs faster high in a gravity field than it does down deeper in a gravity fiels. So this effect tends to make the clocks run faster.

Why do clocks lose time at higher altitudes?

The greater distance of the clock from the centre of the earth the lower the force of gravity and hence the slower the pendulum will swing so that the clock will lose time. In fact, by deploying two identical extremely accurate clocks at different levels of altitude scientists were able to measure the difference in the levels of altitude.

How does altitude affect the speed of a pendulum clock?

And acceleration due to gravity is inversely related to square of the distance from the center of the earth. Thus, higher the altitude, lesser the acceleration due to gravity, and greater the time period.And it will lose time. Originally Answered: If a pendulum clock is taken to a mountaintop, does it go faster or slower?

How does gravity affect the speed of a clock?

It is only relative to a reference frame with weaker gravity that his time runs slow. A person in strong gravity therefore sees his clock run normal and sees the clock in weak gravity run fast, while the person in weak gravity sees his clock run normal and the other clock run slow.

What we need to add is a mechanism that regulates how fast the weight can fall, allowing the whole timekeeping mechanism to advance so the second hand moves one second on the dial (and only one second) in a time of one second. That’s what the pendulum does.

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.

How does a pendulum keep a clock on?

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.

What is the use of a pendulum in music?

The pendulum is also used for identifying the beats. It is interesting to note that the time period of the pendulum remains constant even if the amplitude is changed but if the acceleration due to gravity changes the time period of the simple pendulum also changes.

What is the period of a pendulum?

Galileo discovered that a pendulum’s period (time to swing to one extreme of its arc to the other) depended solely on its length (not its mass, or the speed or amplitude of swing). Without the pendulum and its associated escapement, the hands of the clock would whizz around until the clock weight hit the bottom of the case.

How does a pendulum swing work in real life?

In reality, each swing sees friction and drag steal a bit more energy from the pendulum and it gradually comes to a halt. But even as it slows down, it keeps time. It doesn’t climb as far, but it covers the shorter distance more slowly—so it actually takes exactly the same time to swing.
