## What is simple pendulum answer?

The simple pendulum is **another mechanical system that moves in an oscillatory motion**. It consists of a point mass 'm' suspended by means of light inextensible string of length L from a fixed support as shown in Fig. 2.8. The motion occurs in a vertical plane and is driven by a gravitational force.

**What is simple pendulum for kids?**

A simple pendulum **consists of a small metal ball (called bob) or a mass suspended from a fixed point by a long thread such that the bob is free to swing back and forth under the influence of gravity**.

**How do you solve a simple pendulum problem?**

To calculate the length of a simple pendulum, use the formula **L = (T/ 2π)²*g** . Where T is the time period of the simple pendulum and g is the acceleration due to gravity.

**What is a simple pendulum Grade 7?**

A simple pendulum **consists of a light, inextensible and flexible string carrying a heavy but small object, called bob, at its end**. Diagram : It is used in pendulum clocks. It is used to find acceleration due to gravity.

**What happens in a simple pendulum?**

A simple pendulum has a heavy point mass (known as bob) suspended from a rigid support by a massless and inextensible string. **When the bob from its mean position is pulled to one side and then released, the pendulum is set to motion and the bob moves alternately on either side of its mean position**.

**Why is simple pendulum called simple?**

For small displacements of less than 15 degrees, a pendulum experiences simple harmonic oscillation, meaning that **its restoring force is directly proportional to its displacement**. A pendulum in simple harmonic motion is called a simple pendulum.

**What is a pendulum 3rd grade?**

A pendulum is **an object that hangs from a fixed point so it can move freely**. A playground swing is a type of pendulum.

**What is the example of simple pendulum?**

Simple pendulum

Pendulum clock shows time on the basis of swinging mass that is hanging below the clock. This swinging mass also called as pendulum, moves to and fro motion. This type of motion performed by pendulum is simple harmonic motion.

**Why is simple pendulum used?**

Because in simple pendulum the bob is a point heavy mass and the string is considered to be massless. But in pendulum of a pendulum clock, the bob is not a point mass and also the string is not massless.

**How do you use a pendulum formula?**

Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant. The formula for the period T of a pendulum is **T = 2π Square root of√ ^{L}/_{g}**, where L is the length of the pendulum and g is the acceleration due to gravity.

## What does the pendulum experiment show?

Wherever you put it, Foucault's Pendulum swings from a motionless point while the earth rotates beneath it. Every point of the universe is a fixed point: all you have to do is hang the Pendulum from it." Foucault's pendulum is an easy experiment demonstrating **the Earth's rotation**.

**How do you make a pendulum step by step?**

**What to do:**

- Tie a weight onto the end of the piece of string.
- Make a loop at the other end of the string.
- Screw the hook into the piece of wood and balance the wood between the backs of two chairs.
- Put the loop of string over the hook. ...
- Start the weight swinging and time how long it takes to make 20 swings.

**What is a simple pendulum and its time period?**

The time period of a simple pendulum is **equal to the time it takes to complete one Oscillation**. T=2π√lg→ Length of the string of the pendulum.

**Why do simple pendulums rest?**

**Air friction causes the oscillating pendulum to damp** and thus eventually it comes to rest after some time.

**What are the types of simple pendulum?**

The various kinds of pendulums include the **bifilar pendulum, the Foucault pendulum, and the torsion pendulum**.

**What is the first law of simple pendulum?**

1. The first law of the simple pendulum states that **the period of oscillation of a simple pendulum of constant length is independent of its amplitude, provided the amplitude is small**.

**What is a pendulum and how does it work?**

A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.

**What factors affect simple pendulum?**

Pendulums are pretty simple devices, and the factors that could affect their motion are the length of the string, the weight of the bob, and the size of the swing. Galileo experimented to determine which of these variables determined how often a pendulum swings.

**What are the laws of simple pendulum?**

**State the Law of Simple Pendulum**

- A simple pendulum's period is directly proportional to the square root of its length.
- A simple pendulum's period is inversely related to the square root of gravity's acceleration.
- A simple pendulum's period is independent of its mass.

**What determines the period of a pendulum?**

The only things that affect the period of a simple pendulum are **its length and the acceleration due to gravity**. The period is completely independent of other factors, such as mass.

## How do you find the speed of a pendulum?

And, ϕ is the initial phase of the particle. Hence, the formula for speed of the pendulum at any point comes out to be **Aωcos(ωt+ϕ)**.

**What is the conclusion of simple pendulum?**

conclusions: Galileo also noticed that the period of the pendulum is not dependent on the material from which it is made or on its weight. The pendulum's period is influenced by its length alone. The longer the pendulum, the longer its period.

**Why do pendulums change direction?**

**It's the Earth which is rotating underneath the pendulum**, which makes it appear that the pendulum is in fact changing direction. At the North Pole, the pendulum would appear to rotate through a whole 360 degrees once a day, because the Earth rotates all the way round underneath it.

**What happens when pendulum increases?**

The time period of a pendulum is directly proportional to the square root of the length of the pendulum. So, if the length increases, **the time period of the pendulum increases accordingly**.

**What is simple pendulum and compound pendulum?**

A simple pendulum is represented by a mass of no size attached to an string of with no mass. A compound pendulum represents a real object that is swinging about a point other than its center of gravity. For the simple pendulum all you need to know is its mass and the distance to the pivot.

**What is a pendulum quizlet?**

Terms in this set (26) What is a pendulum anyway? **something hanging from a fixed point which, when pulled back and released, is free to swing down by gravity and then out and up because of its inertia, or tendency to stay in motion**.

**What are the three laws of simple pendulum?**

**According to the laws of simple pendulum.**

- A simple pendulum's period is directly proportional to the square root of its length.
- A simple pendulum's period is inversely related to the square root of gravity's acceleration.
- A simple pendulum's period is independent of its mass.

**Is pendulum and simple pendulum same?**

A pendulum is a weight or body hanged from a fixed point so that it will swing back and forth. There are many different types of pendulums are there. **Simple pendulum and Compound pendulum are the two types among the many different types of the pendulum**.

**What is the time period of the pendulum answer?**

A pendulum clock takes 1 s to move from one extreme to the other extreme, so its time period is **2 s**. Note: The vertical distance between the point of suspension and the centre of mass of the suspended body (when it is in the mean position) is called the length (L) of the simple pendulum.

**What is a pendulum called?**

It may be called a **"bob"** because its vertical position "bobs" up and down while its horizontal motion moves side to side.

## What is second pendulum short answer?

A seconds pendulum is **a pendulum whose period is precisely two seconds**; one second for a swing in one direction and one second for the return swing, a frequency of 1/2 Hz.
