Yes. The velocity can change if the speed remains constant and the direction changes.

Can the speed of an object changes if there is constant velocity?

No, constant velocity implies constant speed. But velocity can change even when speed remains constant, since speed is a scalar quantity but velocity is a vector quantity.



Can an object be accelerating if it has constant velocity?

No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.


If the instantaneous speed of an object remains constant can its instantaneous velocity change?

Yes. Velocity is speed and direction so it can change velocity by changing direction.


If the instantaneous velocity of an object remains constand can its instantaneous speed change?

No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.


The velocity of an object can what if the speed of an object remains constant?

The velocity can still change, even if the speed doesn't. This is because velocity is a vector - not only the magnitude is important, but also the direction.


What is the acceleration of a object that moves at constant velocity?

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


For an object to be moving at a constant velocity is it necessary for it to be moving in a straight line?

Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.


Which quantity remains constant when the net force on an object is increase?

When net force on an unconstrained object changes, the object's acceleration, velocity, position, and possibly speed and shape all change. Its mass remains constant.


Is it possible that the velocity of a body changes and its acceleration remains constant?

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.


What are the conditions for an object to stay at rest to keep moving at constant velocity or to move with increasing velocity?

If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction.

If an object has constant velocity what is its acceleration?

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


What are the conditions of an object to stay at rest to keep on moving at constant velocity or to move with increasing velocity?

If the sum of all forces on an object is zero, then the object remains in constant velocity. Constant velocity means motion in a straight line at a constant speed. "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction. If the sum of the forces is in the same direction as the object's motion, then the object must speed up.


If an object is being accelerated can its velocity be constant?

No. Acceleration is any change of velocity.But its speed can be constant.


When does the speed of an object change?

An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.


Is there an acceleration when an object traveling at constant velocity and why?

No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.


Can an object traveling at constant velocity have acceleration why?

If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.


Can an object with constant velocity be accelerating?

No, since acceleration is defined as a change in velocity. If there is no change, there is no acceleration.
