Difference Between Simple Pendulum and Compound Pendulum

A simple pendulum is represented by a mass of no size attached to an string of with no mass. A compound pendulum represents a real object that is swinging about a point other than its center of gravity. ... For the compound pendulum you need to know its mass, its moment of inertia about the pivot point.

What is the basic difference between simple and compound pendulum?

The main difference between simple pendulum and compound pendulum is that, in a simple pendulum, the distance between the centre of gravity of the suspended body and the axis of suspension is large compared to the dimensions of the suspended body whereas, in a compound pendulum, the dimensions of the suspended body are ...

What is compound pendulum?

In pendulum. 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 difference between a simple pendulum and a physical pendulum?

A Simple Pendulum Is A Physical Pendulum With A Simple Moment Of Inertia (I = ML^2). A Simple Pendulum Has No Mass. A Physical Pendulum Has No Physical Length. There Is No Difference, They Are Different Names For The Same Thing.

Why compound pendulum is preferred than simple pendulum?

This is due to an ideal simple pendulum cannot be realized underlaboratory condition whereas the compound pendulum is preferred for determination theacceleration due to gravity because it moves as one rigid body and the moment of inertia ofthe whole body is take into an account.

Why do we use compound pendulum?

Abstract. The compound pendulum is a standard topic in most intermediate physics courses and this article describes its use to determine the gyradius and center of mass position of Olympic class sailboat hulls by measuring the oscillation period on two pivot points a known distance apart.

Why bar 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. It is in the form of a rectangular bar with holes drilled along its length at equal separation.

What is the principle of katers pendulum?

According to the principle of KAter's pendulum, when the pendulum is suspended upside down from the centre of its oscillation, the period of the swing remains unchanged and the new oscillation centre is the old pivot point.

What is radius of gyration of compound pendulum?

Mathematically the radius of gyration is the root mean square distance of the object's parts from either its center of mass or a given axis, depending on the relevant application. It is actually the perpendicular distance from point mass to the axis of rotation.

Why do shorter pendulums swing faster?

Why does the angle the pendulum starts at not affect the period? (Answer: Because pendulums that start at a bigger angle have longer to speed up, so they travel faster than pendulums that start at a small angle.)

What is the law of simple pendulum?

The time period of the simple pendulum is directly proportional to the square root of its length. ... This property is known as the law of length. The time period of a simple pendulum is inversely proportional to the square root of the acceleration due to gravity at that place.

What is the meaning of simple pendulum?

A simple pendulum consists of a mass m hanging from a string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion. ... with being the natural frequency of the motion.

What are the forces acting on a pendulum?

There are two dominant forces acting upon a pendulum bob at all times during the course of its motion. There is the force of gravity that acts downward upon the bob. It results from the Earth's mass attracting the mass of the bob. And there is a tension force acting upward and towards the pivot point of the pendulum.
