What is length of simple pendulum?
The time period of a simple pendulum: It is defined as the time taken by the pendulum to finish one full oscillation and is denoted by âTâ. Length of a simple pendulum: It is defined as the distance between the point of suspension to the centre of the bob and is denoted by âlâ.
What is effective length of simple pendulum?
Effective length of a simple pendulum is the distance between the points of suspension and the centre of the bob.
At what position does the pendulum have maximum and minimum velocity?
A pendulum reaches its maximum velocity when the block is at its lowest point (the pendulum is vertical and pointing straight down). We can then use the expression for conservation of energy to determine the maximum height of the block.
What is the aim of simple pendulum experiment?
The goal of this experiment was to determine the effect of mass and length on the period of oscillation of a simple pendulum. Using a photogate to measure the period, we varied the pendulum mass for a fixed length, and varied the pendulum length for a fixed mass.
Does a simple pendulum stop finally why?
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.
Why did pendulum stop?
A pendulum stops oscillating because it loses energy when it is converted into heat. Even without air friction, the friction which exists with the point around which the pendulum rotates causes the system to lose kinetic energy and eventually stop.
Do pendulums ever stop?
No. A pendulum can only stop when its gravitational potential is lowest and it no longer has energy driving it. It is moving with maximum speed at its lowest point because this is where it has minimum gravitational potential energy and maximum kinetic energy.
What happens to a pendulum in vacuum?
In a vacuum with zero air resistance, such a pendulum will continue to oscillate indefinitely with a constant amplitude. However, the amplitude of a simple pendulum oscillating in air continuously decreases as its mechanical energy is gradually lost due to air resistance.
What makes a pendulum swing faster?
The swing rate, or frequency, of the pendulum is determined by its length. The longer the pendulum, whether it is a string, metal rod or wire, the slower the pendulum swings. Conversely the shorter the pendulum the faster the swing rate.
Why does the length of a pendulum affect its frequency?
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. A pendulum with a longer string has a lower frequency, meaning it swings back and forth less times in a given amount of time than a pendulum with a shorter string length.
What does period of pendulum depend on?
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.
What does Barton’s Pendulum show?
Forced vibration can be illustrated by a simple experimental setup called Barton’s pendulums. Essentially a large pendulum is used to provide a driver frequency which will make the other, smaller pendulums oscillate at the same rate. The frequency at which it would oscillate at without the smaller pendulums.
