Question

5. what is pendulum ? Define (A) time period of pendulum
b) Oscillation​

Answer 1

Answer:

Explanation:

a} A pendulum has a heavy point mass (known as bob) suspended from a rigid support by a massless and inextensible string. When the bob from its mean position is pulled to one side and then released, the pendulum is set to motion and the bob moves alternately on either side of its mean position.

b} One complete to and fro motion of the pendulum is called one oscillation

Answer 2

Answer:

Ans 5) A chain or stick with a heavy weight at the bottom that moves regularly from side to side to work a clock.

a)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.

b)Oscillation is the repetitive variation, typically in time, of some measure about a central value or between two or more different states. The term vibration is precisely used to describe mechanical oscillation. Familiar examples of oscillation include a swinging pendulum and alternating current.
