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

  1. Apr 4, 2011 #1
    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.
