The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.

NO,velocity changes.
The statement is false because when going around a curve, the motion is not in a uniform direction.
Constant speed around a curve is changing velocity.
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.
No. It can keep a constant SPEED in a curve. But if the direction changes, then that's a change of velocity, and the direction in a curve is constantly changing.
Yes, the velocity is changing. Velocity is a quantity composed of the speed and the direction of motion. Constant velocity means: Constant speed, in a straight line. If the direction is changing, then the velocity is changing, even if the speed is constant.
If the speed is constant, the acceleration is toward the center of the circle.
NO,velocity changes.

yes
Constant speed around a curve is changing velocity.
Yes. The simplest example is an object moving at a constant speed in a circle.
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.
This may have been the result of steering the car around a curve in the road while maintaining constant speed.
It goes in to uniform motion
It goes in to uniform motion
No. It can keep a constant SPEED in a curve. But if the direction changes, then that's a change of velocity, and the direction in a curve is constantly changing.
