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.
What is difference between simple pendulum and physical pendulum?
With the simple pendulum, the force of gravity acts on the center of the pendulum bob. In the case of the physical pendulum, the force of gravity acts on the center of mass (CM) of an object. ... The force of gravity acts on the center of mass (CM) and provides the restoring force that causes the object to oscillate.
What is the period for a physical pendulum?
The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity. The period of a physical pendulum T=2π√ImgL T = 2 π I m g L can be found if the moment of inertia is known. The length between the point of rotation and the center of mass is L.
What are the example of physical pendulum?
A physical pendulum refers to an object which oscillates back and forth, in contrast to the rather idealized simple pendulum where all the mass is concentrated in a single point (usually the mass hanging on the end of the massless rope). One example of a physical pendulum is a baseball bat swinging back and forth .
What are the things to be considered in describing the motion of a physical pendulum the mass of the object gravity and axis of rotation?
What are the things to be considered in describing the motion of a physical pendulum? The mass of the object, gravity and axis of rotation. In this case, a rigid body – instead of point mass – is pivoted to oscillate as shown in the figure. There is no requirement of string.
What are 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 principle of KAter’s 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 do you mean by physical pendulum?
: a rigid body so mounted on a horizontal axis through its center of suspension that when the body is displaced it vibrates freely about its position of equilibrium —distinguished from simple pendulum.
Does physical pendulum depend on mass?
The period of a pendulum does not depend on the mass of the ball, but only on the length of the string . ... With the assumption of small angles, the frequency and period of the pendulum are independent of the initial angular displacement amplitude. A pendulum will have the same period regardless of its initial angle.
What are the types of pendulum?
The various kinds of pendulums include the bifilar pendulum, the Foucault pendulum , and the torsion pendulum.
Does gravity affect pendulum period?
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.
What is the maximum angle of a pendulum?
Paul Appell pointed out a physical interpretation of the imaginary period: if θ 0 is the maximum angle of one pendulum and 180° − θ 0 is the maximum angle of another, then the real period of each is the magnitude of the imaginary period of the other.
What type of motion represents pendulum?
The massive object is affectionately referred to as the pendulum bob. When the bob is displaced from equilibrium and then released, it begins its back and forth vibration about its fixed equilibrium position. The motion is regular and repeating, an example of periodic motion .
How would you describe the motion of a pendulum?
For the pendulum, the bob moves back and forth . This back and forth motion is called “oscillation.” Its position is said to oscillate back and forth. The period is the amount of time it takes the bob to make one round trip.
What is the frequency of a pendulum?
Thus, the frequency of the pendulum defines how many times the pendulum moves back and forth in a specific period of time . For example, how many times the pendulum moves back and forth in 60 seconds. The frequency of the pendulum is determined by its length. It means shorter the pendulum, the swing rate will be more.
