Because there is no tangential force acting on the object in uniform circular motion. The proof that there is no tangential component of acceleration is the fact that the tangential component of velocity is constant.
Centripetal force is the resultant force acting towards the centre of orbit of an object undergoing uniform circular motion.
A body can execute circular motion only if there's a force acting on it, directedtowards the center of the circle. Without that force, circular motion isn't possible.If you expected us to get into "centrifugal" force, forget about it. No such force exists.
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.
In order for an object to be in constant uniform motion ... that is, un-accelerated, with constant speed and direction of motion ... the vector sum of all forces acting on it must be zero.
No

The type of circular motion on a Ferris wheel without stopping is an example of uniform circular motion. In this type of motion, the speed of the object remains constant, but its direction changes continuously, moving in a circle at a consistent rate.

It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.
As force acting in a circular path is always tangential to the path
It travels in uniform motion when there are no net forces acting on it.
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
Newton's first law of motion states that an object in motion will continue moving in a straight line at a constant speed unless acted upon by an external force. In the context of circular motion, a centripetal force is required to constantly change the direction of the object's velocity, keeping it moving in a circular path. Without this centripetal force, the object would continue in a straight line due to its inertia.
