' uniform motion in a circle in which speed is constant but velocity is changing'?

This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.

What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
Acceleration is an increase of speed during a given interval of time?
No. It is the change in velocity (not speed) during a given interval of time. It can be an increase or a decrease although a decrease is also called a deceleration.The distinction between velocity and speed can best be illustrated by an object going round in a circle at a constant speed. It is changing direction all the time so that its velocity is constantly changing. It is constantly accelerating even though it is travelling at constant speed.
A car moves in uniform circular motion around a curve in the road What is the direction of the car's acceleration?
If the speed is constant, the acceleration is toward the center of the circle.
Why the displacement time graph is parabola?
The nature of displacement-time graph is parabolic if the acceleration is constant(uniform). When acceleration is constant, displacement is directly proportional to the square of time which results into a parabolic structure of graph.
If a particle moves in circle with constant speed its angular momentum about the center of circle?
The angular momentum is a constant.

What is uniform in uniform circular motion?
The speed of the object in motion, the radius of the curve in which it moves, the force acting on it to keep it moving in a circle, its angular velocity, and its centripetal acceleration, are all constant. Notice that its linear velocity is not constant, because the direction of its motion is always changing. Although I guess you'd have to say that its velocity is constant in polar coordinates, because the radial and tangential components are constant.
Can a body have constant velocity when it has constant speed?
Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).
Can an object have a constant speed and the varying velocity at the same time explain?
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
What is the differnce between velocity and speed?
Velocity is a vector quantity. So direction is important But speed is a scalar. Body moving around a circle may go with uniform speed but not with uniform velocity as direction is changing continuously
Can a body have constant speed and still have a varying velocity?
Yes, if you are going in a circle or otherwise changing direction.
Can a body have a constant velocity and still have a varying speed?
Yes, if you are going in a circle or otherwise changing direction.
Can a body have a constant velocity and still have varying speed?
Yes, if you are going in a circle or otherwise changing direction.
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
Describe a situation in which the car has zero speed but has a definite acceleration?
An object moving at constant speed in a circle. Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is accelerating.
If a car drove a around in a circle would that be constant velocity?
No. Velocity is a 'vector', which means it's a measurement that has both magnitude and direction. The magnitude is what we usually call the 'speed'. For an object moving in a circle, it could have constant speed ... the velocity could have constant magnitude ... but there's no way the whole velocity vector could be constant, because the direction is always changing. Constant velocity is very easy to recognize ... the object is moving at a steady speed, in a straight line.
Under what circumstances can an object moving with an constant speed (uniform magnitude oits velocity) have an acceleration?
When the direction changes. A simple case is an object moving in a circle, at constant speed.
