 # Question: What Forces Act On A Pendulum?

## What is the function of a pendulum?

Pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity.

Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant..

## How long will a pendulum swing?

Here is an extra fun fact. A pendulum with a length of 1 meter has a period of about 2 seconds (so it takes about 1 second to swing across an arc). This means that there is a relationship between the gravitational field (g) and Pi.

## What does pendulum mean?

A pendulum is something hanging and swinging freely from a fixed point. … Pendulum comes from the Latin word pendulous, meaning “hanging down.” If someone hangs a pocket watch in front of you and swings it back and forth, saying, “You’re getting very sleepy,” they’re mimicking the movement of a pendulum.

## How do I keep my pendulum swinging?

How do I keep my pendulum swinging?Make it heavy (and, specifically, dense). The more mass a pendulum has, the less outside influences such as air resistance will degrade its swing.Put it in a vacuum.Use an escapement mechanism.Give it a large initial swing.

## What forces act on a swing?

The forces acting on a swing rider are the tension in the chain and the weight of the rider. Since the swings travel in a circle, the resultant force is the centripetal force.

## How does a pendulum work physics?

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.

## Why doesn’t mass affect a pendulum?

The reason the simple pendulum has no dependence on mass is because the mass gets to “count” for two different things. (The same thing happens in freefall motion, where all things of all weights fall at the same rate.) Mass counts for inertia, or the “m” in “F=ma”.

## Does angle affect a pendulum?

The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. … With the assumption of small angles, the frequency and period of the pendulum are independent of the initial angular displacement amplitude. A pendulum will have the same period regardless of its initial angle.

## Does mass affect 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.

## What factors affect the swing of a pendulum?

The forces of gravity, the mass of the pendulum, length of the arm, friction and air resistance all affect the swing rate.Motion. Pull a pendulum back and release it. … Length. The swing rate, or frequency, of the pendulum is determined by its length. … Amplitude. … Mass. … Air Resistance/Friction. … Sympathetic Vibration.

## What is the motion of a pendulum called?

For the pendulum, the bob moves back and forth. This back and forth motion is called “oscillation.” Its position is said to oscillate back and forth. Period. The period is the amount of time it takes the bob to make one round trip.

## Why does a pendulum eventually stop swinging?

When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.
