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.
Does friction affects velocity ratio?
No. The velocity ratio remains constant but the friction absorbs power.
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 there is no external force acts on a system of particles the velocity of the centre of mass is?
Velocity remains constant if no external force acts.
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 happens to the velocity of an object even if the speed of an object remains constant?
Velocity can change even if speed is constant.

What Value remains constant in ultrasonic testing?
In general ultrasonic velocity is considered as a constant value relative to the material.
When there is no external force acts on a system of particles the velocity of the centre of mass is?
Velocity remains constant if no external force acts.
When air resistance balances the weight of an object that is falling the velocity remains blank?
Constant
What happens to light when it travels from air into denser?
its frequency remains constant but velocity changes.
Does the speed of a car moving in a circular path at 15 mph remain constant Or does the acceleration or its velocity remains constant?
The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle
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.
Does the horizontal line on the velocity vs time graph indicate a constant and positive acceleration?
Ahorizontal line on a velocity vs time graph does not indicate any acceleration because there is no slope. Speed remains constant.
Which physical quantity remains constant in an elastic collision?
In a uniform circular motion,the magnitude of velocity remains constant,that is speed is constant,however due to change in direction in circular path constantly the motion is accelerated due to change in velocity.
