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.


When can an object a constant speed but not a constant velocity?

Consider an object turning in a circle at a constant speed. Because velocity is not just the value of speed, but also the direction in which the object is moving, the velocity would not be constant.


Can an object have a varying speed if its velocity is constant?

No, velocity is a vector quantity and measures both speed and direction. If the velocity of an object is constant then that would also mean the speed would stay constant.


When an object moves with constant velocity does its average velocity during a time interval differ from its instantaneous velocity at any instant?

No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.


If the mass of a moving object is doubled with no change in velocity what would be the change in momentum?

If the mass doubles and the velocity is constant, then the momentum doubles. p = m * v where p is the momentum, m is the mass, and v is the velocity.

What happens to the velocity of an object even if the speed of an object remains constant?

Velocity can change even if speed is constant.


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.


Velocity can change if the speed and direction of the object changes and can change if the object remains blank fill in the blank?

The answer for the blank is "constant".


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.


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.


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.


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.


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.


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.
