Final answer:
The acceleration of an object can vary during a variable transitory increase. It can either remain constant, decrease, increase, or fluctuate depending on the specific motion.
Step-by-step explanation:
The acceleration of an object during variable transitory increase can vary depending on the specific motion. If the object's acceleration remains constant, it will maintain the same rate of change in its velocity throughout the increase. If the acceleration decreases, it means the object's velocity is increasing at a decreasing rate. Conversely, if the acceleration increases, the object's velocity is increasing at an increasing rate. Lastly, if the acceleration fluctuates, the object's velocity will change irregularly.
