Answers
Explanation:HII MATE ,HERE'S THE ANSWER
1. oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position.
2.periodic time. The interval of time which elapses from the moment when a planet or comet leaves any point in its orbit, until it returns to it again.

Answer:
Period or periodic time of SHIM:
The time taken by a particle performing simple harmonic motion to complete one oscillation is called the period or periodic time of SHM.

Frequency of SHM: The number of oscillations performed per unit time by a particle executing SHM is called the frequency of SHM.
Amplitude of SHM: The magnitude of the maximum displacement of a particle performing SHM from its mean position is called the amplitude of SHM.
Path length of SHM: The length of the path over which a particle perfoms SHM is twice the amplitude of the motion and is called the path length or range of the SHM.
[Note: The frequency of SHM is equal to the reciprocal of the period of SHM.]
