Because of how big the D is
Direction
velocity
uniform
A force acting on an object will cause it to accelerate. This is one of Newton's Laws. Summarized as No force means no acceleration (the object will remain at rest, or will keep traveling with constant speed and direction until a force acts upon it).
Circular -Brittany Goraczkowski
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
Objects traveling in a circular path accelerate towards the center of the circle due to centripetal acceleration. This acceleration is needed to keep the object moving in a curved path.
Direction
Yes an object can be accelerate if its moving along a curve path because when the object moves along a curve path it has constant speed and there is still change in velocity and change in velocity has acceleration

Circular -Brittany Goraczkowski
As long as the object stays in the same circular path, the acceleration doesn't change. It has to change of the object shifts into a larger or smaller circular path. Just like any other occasion where there's a change of acceleration, it happens when the net force on the object changes.
Mass is costant and can not be altered. It represents quantity of matter in an object.
No ALL matter is in motion.
