What is the conclusion of the pendulum experiment?
The surprising conclusion – the pendulum traverses a longer distance in a shorter time, than in a shorter distance, and its period is shorter. There are a number of reasons why Galileo thought that the period remains constant. One factor which Galileo failed to consider is friction.
What is compound pendulum experiment?
experiment, a compound pendulum with a fixed axis of oscillation but with a movable mass. is used to study the dependence of periodic time on the position of the movable mass and to. determine the gravitational field strength.
What is the hypothesis of the pendulum experiment?
The hypothesis in this case would be, “changing the amount of weight at the end of the pendulum will change the period of the pendulum.” The experiment design would involve measuring the period with one amount of weight, changing the weight without changing any other variables, then measuring the period with the new …
What is the aim of compound pendulum?
Aim: (i) To determine the acceleration due to gravity (g) by means of a compound pendulum. (ii) To determine radius of gyration about an axis through the center of gravity for the compound pendulum.
How does a compound pendulum work?
description. A compound pendulum has an extended mass, like a swinging bar, and is free to oscillate about a horizontal axis. A special reversible compound pendulum called Kater’s pendulum is designed to measure the value of g, the acceleration of gravity.
What is the law of the pendulum?
Also called pendulum law . a law, discovered by Galileo in 1602, that describes the regular, swinging motion of a pendulum by the action of gravity and acquired momentum. the theory holding that trends in culture, politics, etc., tend to swing back and forth between opposite extremes.
How do you perform a compound pendulum experiment?
Performing the real lab: The compound bar pendulum AB is suspended by passing a knife edge through the first hole at the end A. The pendulum is pulled aside through a small angle and released, whereupon it oscillates in a vertical plane with a small amplitude. The time for 10 oscillations is measured.
Why is a compound pendulum used in a pendulum clock?
A compound pendulum has an extended mass, like a swinging bar, and is free to oscillate about a horizontal axis. A special reversible compound pendulum called Kater’s pendulum is designed to measure the value of g, the acceleration of gravity. In effect, the plane of the pendulum’s oscillation rotates freely.
What are the variables in a pendulum experiment?
3 The three pendulum variables In this experiment, the period of the pendulum is the dependent variable. There are three independent variables: the pendulum mass, the amplitude of the swing, and the length of the pendulum string.
What variable affects 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.
Why compound pendulum is called compound pendulum?
Bar pendulum is called compound pendulum because a compound pendulum has extended mass, just like as a swinging bar. A bar pendulum is the simplest form of compound pendulum.
What is the procedure of compound pendulum?
The compound bar pendulum AB is suspended by passing a knife edge through the first hole at the end A. The pendulum is pulled aside through a small angle and released, whereupon it oscillates in a vertical plane with a small amplitude. The time for 10 oscillations is measured.
Does a pendulum undergo simple harmonic motion?
However, if we are careful, a swinging pendulum moves in very nearly simple harmonic motion . The angle of swing must be small and the mass must be large compared to the mass of the string/wire. The restoring force (that is the force towards the centre of the swing) is provided by the vector sum of the two forces acting on the bob.
What are the examples of the pendulum motion?
Pendulum motion appears in religious ceremonies as well. The swinging incense burner called a censer, also known as a thurible, is an example of a pendulum. Pendulums are also seen at many gatherings in eastern Mexico where they mark the turning of the tides on the day which the tides are at their highest point.
What is the purpose of the pendulum?
Pendulums are often used as tools for spiritual healing and inner growth. Defined as objects attached at the end of a string or metal chain, when suspended from a stationary position, a pendulum will swing back and forth or in a circular motion.
What is the amplitude of a pendulum?
Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other.
