Explain the following terms with respect to a
pendulum: time period, oscillation and mean
position.
Answers
Explanation:
Time Period: The time required for one complete oscillation is called time period
Oscillation: The vibratory motion of a pendulum is called oscillations
Position: The state of the pendulum in a specific time
Answer:
Pendulum : 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.
Time Period : 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 “T”. 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 “l”.
Oscillation : The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. All three pendulums cycle through one complete oscillation in the same amount of time, regardless of the initial angle.
Mean Position : Mean position is the position of the bob when the freely suspended pendulum is at rest.
