Answer:
Q1) What is Bob?
Answer:- A bob is the mass on the end of a pendulum found most commonly, but not exclusively, in pendulum clocks.
Q2) What is Simple Pendulum?
Answer:- A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. Pendulums are also used in scientific instruments such as accelerometers and seismometers. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing.
Q3) What is motion of a simple Pendulum?
Answer:- 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.
Q4) What is Mean Position?
Answer:- A mean position is any position that is a moderate position between two other extreme positions. It is understood as a middle-of-the-road position or compromise between two extreme views. In order for a position to be a mean position, it only needs to be more moderate than two identifiable extremes.
Explanation:
1.A bob is the mass on the end of a pendulum found most commonly,
simple pendulum consists of a small metal ball (called bob) suspended by a long thread from a rigid support, such that the bob is free to swing back and forth. The motion of pendulum was first studied by Galileo. ... The to-and-fro motion of a simple pendulum is an example of periodic motion (or oscillatory motion). to-and-fro motion of a simple pendulum is an example of periodic motion (or oscilla
tory motion) .
