 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
constant acceleration means the ____ stays the same, while the ____ changes per each time interval
 A displacement; change in velocity B velocity:change in velocity C change in velocity; displacement D velocity; time
Explanation:

Detailed explanation-1: -Constant acceleration means velocity changing at a constant rate since the rate of change of velocity is acceleration (first equation of motion).

Detailed explanation-2: -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 explanation-3: -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 explanation-4: -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.
