[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]


displacement; change in velocity


velocity:change in velocity


change in velocity; displacement


velocity; time

Detailed explanation1: Constant acceleration means velocity changing at a constant rate since the rate of change of velocity is acceleration (first equation of motion).
Detailed explanation2: Constant acceleration is defined as a change in velocity that does not vary over time. If a car increases its velocity by 20 mph in one minute, then another 20 mph the next, its average acceleration remains constant at 20 mph per minute.
Detailed explanation3: A constant velocity of an object ensures that the rate of change of velocity with time is null, and hence, the acceleration of the object is zero. A constant acceleration of an object ensures that the velocity of the object is changing continuously with time, and the velocity will not be constant.
Detailed explanation4: We know that acceleration is the rate of change of velocity per unit of time. Therefore, if acceleration is constant then it means the velocity changes at a constant rate.
