The answer for the blank is "constant".
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Acceleration, the change of velocity, occurs. DO NOT EVER CALL IT DECELERATION. That term is for the archetypal caudex ( it's latin, look it up)...Hence, acceleration includes both the increase AND decrease in the rate of change in velocity...and there you have it.
Velocity is speed in a direction or speed at an angle. The velocity changes when the speed or angle changes.
Absolutely not.Velocity is speed in a particular direction.Acceleration is the rate of change of velocity. NB that is velocity; if an obect's speed remains the same, but it's direction changes, that is a change in velocity which means there was an acceleration.Momentum is velocity multiplied by mass.
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.

A change in the direction of motion IS a change of velocity,even if the speed doesn't change.
Well, Velocity is speed in a spefic direction so if it changes it direction it changes altogether. Sk8
A change in velocity basically IS a change in motion.
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
velocity
Yes. Acceleration is the change in velocity, and velocity is a vector, which means it has direction. Because an object undergoing uniform circular motion is changing direction, it is changing velocity, and thus, accelerating.
No. Velocity is the present speed and direction of motion.If speed or direction changes, then that's 'acceleration'.
