If the instantaneous velocity of an object is constant then so is acceleration.?

the velocity increases at a constant rate

∙ 14y agoIt does not make sense to say that the instantaneous velocity is constant. Instantaneous velocity by definition means that it is the velocity at a moment of time.
If this is a question on some homework, just say no. The acceleration, or rate of change of the velocity, is not necessarily constant.

When is an object's average velocity equal to its instantaneous velocity?
If the velocity is constant (i.e., there is no acceleration). Terminal velocity is an example, although any constant velocity would fit this description.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
What's the difference between instantaneous velocity and instantaneous acceleration?
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
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.
When is an object's average velocity equal to its instantaneous velocity?
If the velocity is constant (i.e., there is no acceleration). Terminal velocity is an example, although any constant velocity would fit this description.
What is an object doing at the moment it's instantaneous acceleration is zero?
it can be moving at constant velocity or staying still
Can the average speed ever equal the instantaneous speed?
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.

Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
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.
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 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.
When the acceleration of an object is zero what is the velocity at the same time?
As long as acceleration is zero, the object's velocity is constant.
