# Difference between a body in motion with a constant velocity and accelerated motion?

I want to know the comparison between a body in motion with constant velocity and accelerated motion?
Like a body when it is motion with constant velocity its velocity is constant(v =constant) and acceleration (a=0)...???
and when a body is in accelerated motion its velocity will be constant(v =constant) and acceleration is also constant (a =constant) or acceleration has some value.
Please elaborate to make me clearer as possible.!

You assume an accelerated object moves at constant speed. This is the contradiction that confuses you

Acceleration means a change in Cartesian velocity.

Since acceleration is the rate of change of velocity, you cannot have constant velocity with a non-zero acceleration.
