The bearing on a clock pendulum is usually two knife edges with a cross piece balanced upon it supporting the pendulum. Sometimes on cheaper clocks a very thin strip of springy steel is used.

What determines whether a pendulum swings in a plane or describes a three-dimensional path?

A pendulum on a knife edge bearing may swing back and forth in a plane (relative to the Earth). A pendulum suspended from aneedle bearingmay swing in elliptical fashion on the surface of a sphere.For the movement to stay parallel to a plane which is fixed relative to the stars, the pendulum must have a needle bearing but no initial momentum perpendicular to that plane. However, the origin of that plane will follow the daily and yearly movements of its location on the Earth. Relative to the Earth, such a pendulum's path will appear to rotate once around every sidereal day (23 hours, 56 minutes, 4 seconds).


What are the parts of a pendulum?

A pendulum consists of a weight or mass attached to a rod or string that pivots at a fixed point. It swings back and forth under the influence of gravity, following an arc. The key components are the bob (weight), suspension (rod or string), and pivot point.


When a pendulum swing stops its energy is changed into what?

A pendulum will lose energy in two ways: 1. by friction with the air, 2. by friction in its supporting bearing. Both these energy losses will produce heat.


When a pendulum swings and is not continuously pushed it will stop because some of its energy was changed into what?

When a pendulum swings and is not continually pushed, the energy is gradually lost to friction and air resistance, causing the pendulum to slow down and eventually stop. This lost energy is converted into heat due to the friction between the pendulum and the air or any other surfaces it comes in contact with.


Why a compound pendulum is called equivalent simple pendulum?

Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.


How does the length of the pendulum effect the pendulum?

The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.


The weight on a pendulum is called?

The weight on a pendulum is a 'mass' or a 'bob'.


Frictionless pendulum is an example of?

Frictionlist pendulum is an example of the pendulum of a clock, a reversible process, free.


How does the length of a pendulum affect the frequency?

A longer pendulum will have a smaller frequency than a shorter pendulum.


What happens when you double the mass of a pendulum?

Doubling the mass of a pendulum will not affect the time period of its oscillation. The time period of a pendulum depends on the length of the pendulum and the acceleration due to gravity, but not on the mass of the pendulum bob.


Which factor affects the period of the pendulum?

The period of a pendulum is affected by the angle created by the swing of the pendulum, the length of the attachment to the mass, and the weight of the mass on the end of the pendulum.


How to find the length of a pendulum?

The length of a pendulum can be found by measuring the distance from the point of suspension to the center of mass of the pendulum bob. This distance is known as the length of the pendulum.
