Answer 1

Answer:

a.simple 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.

b.Oscillation:It is refered as the movement of a object back and forth in a regular rhythm.

c.Length of pendulum:Length of a simple pendulum is the distance between the points of suspension and the centre of the bob.

d. Time period:Effective length of a simple pendulum is the distance between the points of suspension and the centre of the bob.
