Fill in the blank. If the speed of a moving object does not change, the acceleration of the object must
be blank. (A) Zero, (B) equal to the speed of the object.
To answer this question, we need to understand what is meant by the word
“acceleration.” Acceleration is a measure of how much the speed of an object changes in a particular
amount of time.
In this question, we are told we have a moving object, and the speed of the object
does not change. If we’re told the speed of the object stays the same, we can say the change in its
speed is zero. Therefore, its acceleration must be zero too. We know that the object is not accelerating.
So, we choose option (A) as our answer. If the speed of a moving object does not change, the acceleration of the object must
be zero.
