## How does length of pendulum affect 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.)

**Which pendulum will swing faster?**

Shorter pendulums swing faster than longer ones do, so the pendulum on the left swings faster than the pendulum on the right. pendulums to one side, and then let them swing. Notice that, if you start them swinging at the same time, they return to their starting points at the same time.

**What is the period of a swing?**

The time it takes a pendulum to swing back to its original position is called the period of the pendulum. For example, this is the time it takes a child being pushed in a swing to be pushed and then return back for another push.

### How can you find the period of swing more accurately?

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. Choose the number of swings so that the total time for the measurement is 40 seconds or more.

**How do you find the length of the period of a pendulum?**

A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.

**What affects the swing rate of a pendulum?**

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.

## Do longer pendulums swing faster?

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. On grandfather clocks with long pendulums or clocks with shorter ones, the swing rate depends upon the pendulum’s length.

**Why do shorter pendulums swing faster?**

From the time period formula, time period of the pendulum is directly proportional to the square root the length of the pendulum. When the length of the string is shorter the time period of the pendulum decreases.

**Is the time required to swing to and fro the period on a playground swing longer or shorter when you stand rather than sit explain?**

Is the time required to swing to and fro on a playground swing longer or shorter when you stand rather than sit? When you stand, the pendulum is effectively shorter, because the center of mass of the pendulum (you) is raised and closer to the pivot. So period is less – it takes a shorter time.

### Why does a shorter pendulum swing faster?

Why does the angle the pendulum starts at not affect the period? (Answer: Because pendulums that start at a bigger angle have longer to speed up, so they travel faster than pendulums that start at a small angle.)

**Is it better to start and stop the stopwatch at the end of the swing or at the center?**

It should be about 2 seconds. Notes on measuring period. Start the stopwatch as the weight crosses through the bottom of its swing, stop it also at the bottom of its swing after it has gone through one oscillation. You can make make accurate measurements by timing ten swings of the pendulum.

**How do you find the period of oscillation and length of the thread?**

To measure T, measure the time for 25 or 50 oscillations (swings) and then divide that time by 25 or 50.

- Select a length of L = 115cm (1.
- Practice the applet a few times.
- Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted.

## How does the length of string affect the swing of a pendulum?

When you add a weight to the middle of the other pendulum, however, you effectively make it shorter. Does angle affect period of a pendulum? 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.

**How does the size of the swing affect the swing?**

In this lesson, students observe that the size of the swing does not affect the time it takes for a pendulum to swing back and forth. Just like Galileo, students find that even when a pendulum swings through a small angle, the time of each swing (the period) remains the same as if it swung through a large angle!

**What does it mean when you swing on a string?**

When you are on a swing, you move like a pendulum. A pendulum is a string hanging from a fixed spot with a weight (called a bob) at one end that can swing back and forth. One day in the late 1500s, a budding scientist named Galileo Galilei was sitting in church when he noticed the chandeliers hanging from the ceiling were swinging back and forth.
