displacement is maximum
Acceleration is a vector, so it has both magnitude and direction.A particle in the simple harmonic motion, x = a cos(2t), has an acceleration that varies between positive and negative extremes (+4a and -4a) at the end points of its motion and has zero acceleration as it passes through its center of motion.Here is the mathematics.Position ' x ' = a cos(2t)Velocity ' v ' = dx/dt = -2a sin(2t)Acceleration = dv/dt = -4a cos(2t)The minimum instantaneous magnitude of acceleration is zero,and its most negative instantaneous value is [ -4a ].
A motion is simple harmonic if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean position.
maximum
its is the motion in which acceleration is directly proportion to the displacement from a fix point and always directed towards the center
Acceleration is a change in either the magnitude or direction of velocity, over time. http://en.wikipedia.org/wiki/Acceleration
The acceleration is greatest at the top and bottom of the motion.
If an object moves in a circle at a constant speed, the magnitude of the acceleration won't change.

A body undergoes simple harmonic motion if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean. Provided the amplitude is small, a swing is an example of simple harmonic motion.

No. Simple harmonic motion requires that the acceleration is proportional to the displacement (and in the opposite direction). It is possible to have periodic motion where that is not the case.

simple harmonic motion (SHM) the two summits of motion are an example

When the acceleration is directly proportional to the displacement from a fixed point and always directed towards that fixed point then such an oscillation or vibration is said to be simple harmonic
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
