Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?

No because acceleration is a change in direction or velocity. If yo

Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.

No. The definition of acceleration is a change in velocity, i.e. speed and/or direction. So constant velocity means zero acceleration.

Yes. A body having zero velocity has a constant acceleration of zero.

No, the definition of acceleration is the increase change in velocity over time. An acceleration can also be a decrease in velocity over time. Constant velocity refers to an object that maintains the same velocity as time progresses. If the object has an acceleration, its velocity will not remain constant. In the case of rotational velocity there is a constant internal acceleration that has the magnitude v2/r

the question is very a body does not have acceleration when it is moving with constant velocity ,because a body posses acceleration when its velocity is not remain conserved or constant.yes if a body have constant speed it may have acceleration but not in case of constant velocity.

If your velocity is constant, then your acceleration is zero.

No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.

If you have constant acceleration, then you can't have constant velocity. (Unless the acceleration is constantly zero.)Final velocity = [initial velocity] + [ (acceleration) x (time) ]

there is no acceleration if the body is moving with constant velocity

Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.

Acceleration is change of velocity. If velocity is constant ... "no change" ... then acceleration is zero.

Acceleration is the rate of change of velocity. Constant velocity means zero acceleration.

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.

If the velocity is constant then there is no acceleration. The acceleration is zero.

constant velocity means no acceleration. An object can be moving at constant speed, like a satellite in orbit, but its velocity is changing because direction is changing

An object with constant velocity has no acceleration.

That can't happen. If there is any acceleration at all, then velocity is not constant.

Acceleration is constant.Velocity increases at a constant rate.

No, because acceleration is the rate of change of velocity.

Acceleration is defined as The rate of change of Velocity. Which means that for acceleration there must be Variable Velocity/ Speed. and not uniform

"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.

Yes this is possible, when the velocity is constant. When velocity is constant there is no change in velocity, if there is no change in velocity then is no acceraltion. e.g. : a car traveling at a constant speed of 40m/s

No it cannot. It is either one or the other. For constant velocity, acceleration must be 0, meaning there is no acceleration happening here. If there is constant acceleration, then the velocity is constantly changing.

Answer #1:Yes. A simple case is that of an object moving in a circle at constant speed. Since the accelerationvector points to the center of the circle, the acceleration changes all the time.===================================Answer #2:No.-- If acceleration is variable, that means acceleration is not zero.-- If acceleration is not zero, that means that either speed or direction is changing.-- If speed or direction changes, then velocity is not constant.In the example of circular motion, described in Answer #1, the speed is constant, butthe velocity is not, since the direction of motion is constantly changing.
