Absolutely!
Speed and velocity are not the same.
Speed of merely a scalar with a magnitude whereas velocity is a vector which has both a magnitude AND a direction.
In uniform circular motion, an object can travel around a circular path with a constant speed, but since it is always changing direction (going around the circle), the object is always acceleration, and thus has a constantly changing velocity.
The velocity at any instant of an object traveling around a circular path is pointed tangentially to the circle. As the object moves, the velocity stays tangent to the circle at the location of the object so the velocity is constantly changing. This constant change in velocity is caused by an acceleration...."Centripetal" acceleration which is always pointed radially inward towards the center of the circle.

Yes.
Velocity is a vector quantity, speed id not. So velocity includes direction as well as speed.
As an example, put a lump of poster putty on one blade of the ceiling fan above your bed. Lay back, relax, keep your eyes open and switch the fan on. The fan will rotate a a constant number of revolutions per minute. The lump of poster putty will move at a constant speed, that is it will cover a constant number of inches per second. The velocity of the lump will be continually changing because it's direction of travel is continuously changing although it's speed remains constant.

Definitely yes. A particle in a circular motion, with constant speed has varying velocity. (direction changes continuously)

Velocity is speed AND direction. A car driving at 30 miles per hour in a circle is constantly changing it's velocity but not its speed.

Yes.
Velocity is a vector, in that the *direction* matters as well. Whereas speed is a scalar, in that only the *value* matters.
For example.
Travelling due North at 30mph is a different velocity to travelling due west at 30mph, but the speed is the same.
In circular motion, one is always changing velocity (accelerating) as the direction of motion is always changing. However the speed does not change.

YES, THIS CAN BE HAPPENED ONLY WHEN THE VELOCITY OF THE OBJECT IS CHANGING IN DIRECTION , THE MAGNITUDE OF THE VELOCITY REMAINED CONSTANT.
FOR EXAMPLE, IF THE OBJECT IS MOVING IN A CIRCULER PATH AT A UNIFORM SPEED, IT'S VELOCITY CHANGES AT EVERY MOMENT,BUT SPEED ( WHICH HAS NO DIRECTIONAL PROPERTY ) REMAINS SAME.

Yes, velocity is a vector (it has magnitude and direction) while speed is a scalar ( it has only magnitude). Acceleration is a change in velocity, so if you turn at 10 kph, without slowing down, you still have acceleration.

speed is the same thing as velocity but the diff is direction.. the answer to ur question yes. because an object can be going the same speed but diff direction

yes .
speed is magnitude of velocity.
velocity has both magnitude and direction.
so if u keep magnitude constant and direction changing u ll have constant speed but varying velocity.

convinced. because % is a scalar volume even as speed is a vector volume, it exhibits the instructions and the importance of an merchandise. It replaced into occurred even as the consistent % together a various speed even as the route replaced into change yet in way of continuous %.
