An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".

Constant "velocity" means no acceleration.

What happens to the momentum of an object traveling with a certain velocity if a load is added to it while in motion?

The momentum of an object traveling with a certain velocity will increase if a load is added to it while in motion. This is because momentum is directly proportional to both mass and velocity, so adding mass will result in an increase in momentum as long as the velocity remains constant.


Why does a car traveling at constant speed can accelerate while a car at constant velocity connot?

The question is inherantly flawed. A car traveling at a constant speed cannot accelerate, if it could it's speed would not be constant. "Constant speed" means that speed is not increasing or decreasing but remain consistent over time. For example, if you cover 10 feet during each second, your speed is constant. "Constant velocity" implies constant speed, but it has an additional constraint: you can't change your direction. If you travel constantly at 10 feet per second in a straight line, then your speed is constant and your velocity is constant. But if you travel constantly at 10 feet per second in a wiggly line (or a circle, or anything not straight), then your speed is constant but your velocity is NOT constant. If you travel at a constant speed but change direction, velocity is changed. Or if you travel in the same direction but change the speed, velocity is changed. Average speed is is easier: distance/time So, your question should read: Why can a car traveling at an average speed accelerate, but a car traveling at constant speed cannot? Or Why am I asking the wrong questions?


Can a car move with changing velocity while maintaining constant speed?

Constant speed around a curve is changing velocity.


Differentiate between steady flow and pipe unsteady flow?

The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.

example of a change in acceleration while travelling at constant speed?

An example of a change in acceleration while traveling at constant speed can be observed when a vehicle moves in a circular path or takes a turn. Although the speed remains constant, the direction of the motion changes, which results in a change in velocity. Since acceleration is the rate of change of velocity, this alteration in direction causes a change in acceleration, even when the speed is constant.

Constant speed around a curve is changing velocity.


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

If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.


Traveling down a highway a car changed velocity while its speed remained constant.what would have caused this to happen?

This may have been the result of steering the car around a curve in the road while maintaining constant speed.


Differentiate between steady flow and pipe unsteady flow?

The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.


Why the speed of an object is constant while the velocity is not?

This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.


What is the condition in which a body moving with uniform speed has a variable velocity?

Speed is considered a scalar while velocity is refered to as a vector. A vector can be varied with respect to its direction. Therefore, constant speed while changing direction varies the velocity


Can an objeact have constant speed and but variable velocity?

Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.


Why is it an object can accelerate while travelling at constant speed but not at constant velocity?

Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
