Comprehension If a mass attached to a spring (mass less) is pulled down twice, as far, the force will be twice as much, the resulting acceleration is twice as great, the velocity it acquires in a given time is twice as great, the distance covered in a given time is twice as great, but it has to cover twice as great a distance in order to get back to the origin. In a linear equation the time pattern does not change. If there were no friction, the oscillation stays on with same amplitude. However when there exists a friction of magnitude smaller for small oscillation and larger for larger oscillation the amplitude gets dropped by the same fraction in every cycle. When the displacement from the mean position is doubled, the quantity that will vary will be:
Time period only
Velocity only
Acceleration only
Both (b) and (c).

In amplitude of an oscillation in a reactive to the proceeding one in a system with initial maximum amplitude A0 oscillating in a damping media, the amplitude just after n oscillations will be:

To solve the S.H. equation with friction, one must consider each half separately since.
Friction reverses its direction in each cycle
The S.H. equation will not be linear
Friction is independent of the displacement
All of these
