Final answer:
Variable deceleration is not necessarily the most worrisome type of deceleration; the level of concern depends on the specific situation and context.
Step-by-step explanation:
False
Variable deceleration is not necessarily the most worrisome type of deceleration. The worry associated with deceleration depends on the specific situation and context. For example, if a car is decelerating to avoid a collision, it would be more worrisome than if a car is decelerating to come to a smooth stop at a traffic light.
Thus, it is important to consider the circumstances and consequences of deceleration to determine its level of concern.
