# Quick Answer: Why Does Mass Not Affect A Pendulum?

## How do I keep my pendulum swinging?

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

## Where does energy go when a pendulum stops swinging?

Once the weighted end of the pendulum is released, it will become active as gravity pulls it downward. Potential energy is converted to kinetic energy, which is the energy exerted by a moving object.

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

The time period of a pendulum does not depend on the mass of bob. So if the mass of bob doubled, the time period remains the same.

## What happens to period if mass is doubled?

Thus, if the mass is doubled, the period increases by a factor of √2.

## Does a pendulum tell the truth?

As an example – people use a pendulum to ask if a certain food is good for them by holding it over the item, and if it’s a healthy high vibration food then the pendulum will answer YES.

## Does mass affect pendulum?

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.

## Why does mass not affect period?

The mass of a pendulum’s bob does not affect the period. … As mass increases, so does the force on the pendulum, but acceleration remains the same. (It is due to the effect of gravity.) Because acceleration remains the same, so does the time over which the acceleration occurs.

## Why does a pendulum eventually slow down and stop swinging?

A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. … 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.

## Does mass not affect the period of a pendulum?

The mass of the bob does not affect the period of a pendulum because (as Galileo discovered and Newton explained), the mass of the bob is being accelerated toward the ground at a constant rate — the gravitational constant, g.

## Why won’t the pendulum keep swinging?

Have you recently moved your clock? The reason a clock pendulum often stops swinging, after being moved, is because the clock case now leans at a slightly different angle then it did at its former location. Don’t worry about making your clock absolutely level with the floor and don’t use a level.

## How do you adjust a pendulum mantel clock?

The adjustment nut is a large nut at the bottom of the pendulum just below the large disk or weight called the bob. 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.

## Why does period increase with mass?

You know-both from your own practical experience and from Newton’s second law-that a larger mass will be more difficult to move. The period will increase as the mass increases. More mass-with the same spring-will mean a larger period. … A: A stiffer or stronger spring means a greater force in Newton’s second law, F = ma.

## What affects the swing rate 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.

## Does release angle affect period pendulum?

(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.)

## What makes a pendulum move?

A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. … As it accelerates down toward its lowest point (its midpoint, nearest the ground), this potential energy is converted into kinetic energy (energy of movement) and then, as the bob climbs up again, back to potential energy.

## Why would a pendulum eventually stop?

The pendulum stops eventually because of air resistance. The pendulum loses energy because of friction. Only in a theoretical situation when there is no friction the pendulum will oscillate forever.

## What factors affect pendulum period?

The mass and angle are the only factors that affect the period of a pendulum. b. The mass, the angle and the length are the three variables affecting the period.

## How do you adjust 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.
