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 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.
What remain constant in uniform circular motion?
In uniform circular motion, the speed of the object remains constant as it moves around the circle. However, the velocity of the object changes because the direction of the velocity vector is constantly changing. The centripetal acceleration remains constant in magnitude and always points towards the center of the circle.
Is the velocity constant for an object in uniform circular?
No, the velocity is not constant for an object in uniform circular motion because the direction of the velocity is changing as the object moves around the circle. The magnitude of the velocity remains constant, but the direction is continuously changing.
What is uniform in uniform circular motion?
In uniform circular motion, "uniform" refers to a constant speed of the object moving in a circular path. It means the object is moving around the circle at a consistent rate without speeding up or slowing down. uniform circular motion does not mean that the object is at rest or that the path is a perfect circle.
Which physical quantity changes continuously during uniform circular motion?
The direction of velocity changes continuously during uniform circular motion. The magnitude of velocity remains constant, but its direction is constantly changing as the object moves around the circle.
Can uniform angular velocity has acceleration?
No, uniform angular velocity implies that an object is moving in a circle at a constant rate. Since acceleration is defined as any change in velocity (either speed or direction), if the angular velocity is constant, there is no acceleration present.
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).
Why object moves in a circle have a constant speed and velocity?
An object moving in a circle at a constant speed has a changing velocity because velocity is a vector quantity that includes both speed and direction. In circular motion, the object is constantly changing direction, so its velocity is changing even though its speed remains constant.
When an object does circular motion what is constant?
When an object is performing circular motion, the speed of the object remains constant, while the velocity is constantly changing due to the direction changing. The centripetal force required to keep the object moving in a circle is also constant.
If a car drove a around in a circle would that be constant velocity?
No, if a car is driving in a circle, it is changing direction constantly. Velocity is a vector quantity that includes both speed and direction, so if the direction is changing, the velocity is not constant.
Can uniform velocity appear in circular motion?
No, uniform velocity cannot appear in circular motion because the direction of the velocity is constantly changing in circular motion due to the centripetal acceleration required to keep an object moving in a curved path. Uniform velocity implies constant speed and direction, which is not the case in circular motion.
Why is a particle in uniform circular motion not moving at a constant velocity?
In uniform circular motion, the particle's direction is constantly changing even though its speed may remain constant. Since velocity is a vector quantity that includes both magnitude and direction, the changing direction means that the velocity is also changing. Therefore, the particle is not moving at a constant velocity.
