What is the scientific theory of a pendulum?

Answer 1

The theory of a simple pendulum refers to a relatively huge object hanging vertically by a string from a fixed place and moving in a back and forth motion when displaced. The movement of the huge object or pendulum bob is repetitive and regular.

Answer 2

A simple pendulum consist of a bob suspended from the end of a lightweight cord. The cord cannot stretch and the mass of the cord must be small compared to the mass of the bob. With negligible friction, the motion resembles SHM.

Answer 3

A pendulum measures the ratio between time and gravity. The length between the fulcrum and the center of weight on the end is the part of the pendulum that matters even though the actual pendulum is is longer. Longer pendulums take longer to complete a cycle than shorter pendulums. A child's swing is a long pendulum. Take a string a few inches long, attach a weight to the end, and compare its swing to how it takes a child on a swing to go through one cycle. A grandfather clock has a pendulum with a period of about one second. The length of the pendulum is set at the factory for the average point in the United States. Gravity meters exist. If your Grandfather clock gains or loses time, You can reset the length of the pendulum as determined by a gravity meter. Once you know the gravity and the ratio, you can get the time. For further information concerning the relationship between gravity and time, read Einstein's Theory of Relativity.

Answer 4

A pendulum is a weight suspended from a pivot point that swings back and forth due to the force of gravity. The motion of a pendulum follows the principles of simple harmonic motion, meaning that its movement can be described using mathematical equations involving its length and acceleration due to gravity. The period of a pendulum (time taken for one complete swing) is constant and depends only on its length.

Answer 6

A mass suspended on a string that is allowed to swing freely. Not necessarily a string - the swinging thing on a grandfather clock is a pendulum too.

No!

It is 2*pi*sqrt(L/g)
