On taking the pendulum to the top of a mountain, g will decrease, therefore, T will increase. The pendulum will take more time to complete one vibration, i.e., it will lose time.

## How would the motion of a pendulum change at high altitude?

What would your pendulum do under weightless conditions? The acceleration due to gravity is determined by the mass of the two objects and the distance between those objects. As the altitude increases, the distance between the earth and the bob of the pendulum is increased, thus decreasing gravity.

## Why does a pendulum’s period increase if it’s taken to a higher altitude?

The only things that are capable of affecting the period are are the length of the pendulum and the acceleration due to gravity. Furthermore, decreasing the altitude of the pendulum will increase the force due to gravity, which will resulut in a decreased period.

## Will a pendulum swing forever?

As the pendulum swings back and forth, the balance between the two types of energy changes constantly. At some points in its swing, the pendulum has more kinetic energy. No pendulum can swing forever because the system loses energy on account of friction.

## Where is the pendulum when it has minimum potential energy?

First, let’s take a look at potential energy. When the pendulum is at the bottom of its trajectory, its potential energy will also be at its minimum. This is because the height of the mass attached to the pendulum is lowest at this point.

## What stops a pendulum from 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.

## What affects the period of a pendulum?

This can be explained by examining possible effects of each of the three variables: the length of the string, the mass of the bob, and the angle displaced. The length of the string affects the pendulum’s period such that the longer the length of the string, the longer the pendulum’s period.

## Does angle affect pendulum period?

(Increase the length of the string and increase the angle.) 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.)

## Why does mass not affect period of pendulum?

The mass on a pendulum does not affect the swing because force and mass are proportional and when the mass increases so does the force. As the force increases so does the acceleration and along with gravity are the factors that affect the pendulum swing. Therefore, the mass does not affect the period of the pendulum.

## Does air resistance affect the period of a pendulum?

The air resistance reduces the acceleration and increases the time period of oscillation. The air resistance reduces the velocity of the pendulum and the pendulum gradually comes to rest.

## How does gravity affect period of a pendulum?

As the first formula shows, the stronger the gravitational pull (the more massive a planet), the greater the value of g , and therefore, the shorter the period of oscillations of a pendulum swinging on that planet.

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

This is adjusted by turning the nut at the bottom of the pendulum. Moving it up pushes the “bob” (the round disk) up so the clock will run faster. If you turn the nut as to lower the “bob”, the clock will run slower. The pendulum disk is moved up or down by turning the adjustment nut.

## How do you slow down a pendulum?

To slow down the clock, loosen the adjustment nut (turn it toward your left). The bob will settle lower, making the effective length of the pendulum longer. The clock will run slower. To speed up the clock, tighten the nut (turn it toward your right).
