Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.

Block A
Block B
Two blocks are connected to identical ideal springs and
are oscillating on a horizontal frictionless surface. Block
A has mass m, and its motion is represented by the
graph of position as a function of time shown above on
the left. Block B's motion is represented above on the
right. Which of the following statements comparing
block B to block A is correct?
Because block B covers more distance
A
per cycle than block A, block B takes
more time to complete each cycle.
Because the spring attached to block B
is initially stretched a greater distance,
the spring constant is smaller and
therefore block B has a slower average
(B
speed than block A does.
Because block B has more mass, it has
a slower average speed than block A
does.
Because block B has more mass, its
acceleration is smaller than that of
block A at any given displacement from
the equilibrium position.
