Document Summary
As the object moves through the stages of vibration (going from one extreme to the other by elasticity and inertia), the speed of the movement of the object varies. Acceleration is the rate at which the speed of movement increases. During vibration, the speed increases the most at the two extremes, i. e. , acceleration is greatest at those points. The actual speed or velocity is greatest when the object passes by the point of rest. It"s like two hills and a valley on a roller coaster. At the top of the hill, you aren"t moving rapidly; but you begin to speed up at the greatest rate (i. e. , maximum acceleration). When you reach the low point/valley, you are moving at your maximum speed (i. e. , maximum velocity); but you aren"t speeding up at that point - you aren"t accelerating. Resistance of the surrounding medium (e. g. , air) causes friction.
