When it's moving in a straight line at a constant speed. And it has
nothing to do with my judgment or opinion. That's the definition.
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
there is no acceleration if the body is moving with constant velocity
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path. - See more at: http://www.chacha.com/question/what-is-the-path-of-a-moving-body-whose-acceleration-is-constant-in-magnitude-at-all-times-and-is-perpendicular-to-the-velocity#sthash.pqrkWxfT.dpuf
A body is moving at constant velocity including zero at Equilibrium Condition, No change of energy or zero force. With force a body can accelerate, move with increasing velocity.
Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).
A feather with no momentum maintains constant velocity. Momentum is defined as the quantity of motion of a moving body, measured as a product of its mass and velocity.
Nein. If it's moving, by definition it has non-zero velocity.
Uniform Constant Deceleration
The speed can be constant but the velocity can't, because the directionof motion ... which is a component of velocity ... is changing. Also the velocity of a moving body changes when its speed changes but remains moving towards the same direction ... :) :]
