# What length of pendulum would have a 1 s period on Mars?

## What length of pendulum would have a 1 s period on Mars?

Therefore, for a pendulum of length l=3.74π2 m≈0.09 m l = 3.7 4 π 2 m ≈ 0.09 m will have a period of one second on Mars. where m= mass attached to the spring m = mass attached to the spring and k= spring/force constant k = spring/force constant .

## What does period of pendulum depend on?

The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.

What is the time period of a pendulum?

The time taken to complete one oscillation is known as the time period of the pendulum. Therefore 1.6s is the time period of the pendulum.

What is yes and no on a pendulum?

Then do this for the “no” signal, again while demonstrating it. Here’s an example of how to program the “yes” signal: Holding the pendulum in position, say “When I ask a question and the answer is yes, move like this, in a clockwise circle.” (or whatever signal you’ve chose for “yes”).

### What causes a pendulum to swing?

Function. The science behind the pendulum is explained through the forces of gravity and inertia. The Earth’s gravity attracts the pendulum. This swinging-back-and-forth force continues until the force that started the movement is not stronger than gravity, and then the pendulum is at rest again.

### Does amplitude affect period of a pendulum?

Increasing the amplitude means that there is a larger distance to travel, but the restoring force also increases, which proportionally increases the acceleration. This means the mass can travel a greater distance at a greater speed. These attributes cancel each other, so amplitude has no effect on period.

What is the relationship between pendulum length and period?

The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.)

What happens to the period of a pendulum when the amplitude is doubled?

(i) As time period of oscillation os simple pendulum T=2π√lg is independent of amplitude of oscillation, hence time period of oscillation does no change with the change in the amplitude of oscillation. When amplitude A is doubled, then max, acceleration becomes double.

## Does angle affect period of pendulum?

Finally, the angle that the pendulum swings through (a big swing or a small swing) does not affect the period of the pendulum because pendulums swinging through a larger angle accelerate more than pendulums swinging through a small angle.

## How do I keep my pendulum swinging?

There are several things that you can do to make a pendulum swing for a long time:

1. Make it heavy (and, specifically, dense). The more mass a pendulum has, the less outside influences such as air resistance will degrade its swing.
2. Put it in a vacuum.
3. Use an escapement mechanism.
4. Give it a large initial swing.

Which pendulum will swing faster?

The swing rate, or frequency, of the pendulum is determined by its length. The longer the pendulum, whether it is a string, metal rod or wire, the slower the pendulum swings. Conversely the shorter the pendulum the faster the swing rate.

How can you make a pendulum experiment more accurate?

Improve the accuracy of a measurement of periodic time by:

1. making timings by sighting the bob past a fixed reference point (called a fiducial point )
2. sighting the bob as it moves fastest past a reference point. The pendulum swings fastest at its lowest point and slowest at the top of each swing.

### How would you most accurately time one swing of a pendulum?

Moving the bob up decreases the pendulum’s length, causing the pendulum to swing faster and the clock to gain time. Some precision clocks have a small auxiliary adjustment weight on a threaded shaft on the bob, to allow finer adjustment.

### How do you know when your pendulum has completed 1 oscillation?

One oscillation is completed by a pendulum when it starts from the extreme position A and moves to the other extreme position B and then returns to A. The time to complete one oscillation is called the time period. The time period of oscillation remains constant.

What is the frequency of a pendulum?

The frequency of a pendulum is how many back-and-forth swings there are in a second, measured in hertz. f = [√(4.9)]/6.28 = 2.21/6.28 = 0.353 Hz.

What is the time taken by a pendulum to complete one oscillation?

Time period: It is the time taken by the body to complete one oscillation cycle. It is measured in seconds (sec). As per the question, the time taken by the pendulum to complete one oscillation is called the time period.

## What is the best method to find the time period?

A simple way to measure the pendulum’s period fairly precisely is to start the pendulum swinging, and measure the time required for a large number of FULL swings – 40, 50, or so.

## What is the period of motion?

Periodic motion, in physics, motion repeated in equal intervals of time. In each case the interval of time for a repetition, or cycle, of the motion is called a period, while the number of periods per unit time is called the frequency.

What is relation between frequency and time period?

Sound | Short/Long Answer Questions The number of times a cycle is completed in a second is the frequency. The time taken to complete one vibration is called time period. Frequency and time period is inversely proportional, the number of vibrations per second is frequency.

How do you calculate time period?

How to get period from frequency?

1. The formula for period is T = 1 / f , where “T” is period – the time it takes for one cycle to complete, and “f” is frequency.
2. To get period from frequency, first convert frequency from Hertz to 1/s.
3. Now divide 1 by the frequency. The result will be time (period) expressed in seconds.

### How do you convert time to frequency?

Frequency is expressed in Hz (Frequency = cycles/seconds). To calculate the time interval of a known frequency, simply divide 1 by the frequency (e.g. a frequency of 100 Hz has a time interval of 1/(100 Hz) = 0.01 seconds; 500 Hz = 1/(500Hz) = 0.002 seconds, etc.)

### Why is the period?

The ovaries release the female hormones estrogen and progesterone . These hormones cause the lining of the uterus (or womb) to build up. The built-up lining is ready for a fertilized egg to attach to and start developing. If there is no fertilized egg, the lining breaks down and bleeds.

What is the period in free oscillations?

The time taken for one complete oscillation is called Period. The number of cycles/oscillations per second is called the frequency of oscillation. The maximum displacement from the mean position is called the amplitude of oscillation.

What are free oscillations give two examples?

Some examples of free vibrations are oscillations of simple pendulum, oscillations of object connected to a horizontal spring, sound produced by tuning fork in short distance, notes of musical instruments, organ pipe, etc.

## What is forced SHM?

When we displace a pendulum from its equilibrium position, it oscillates to and fro about its mean position. Eventually, its motion dies out due to the opposing forces in the medium. This type of motion is known as forced simple harmonic motion. …

## Where is damping used?

Damping, in physics, restraining of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipation of energy. Unless a child keeps pumping a swing, its motion dies down because of damping. Shock absorbers in automobiles and carpet pads are examples of damping devices.
