Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
constant velocity means no acceleration. An object can be moving at constant speed, like a satellite in orbit, but its velocity is changing because direction is changing
A car moving at constant speed in a straight line is also moving at constant velocity.
there is no acceleration if the body is moving with constant velocity
constant
Photon or rather light
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
A car moving at constant speed in a straight line is also moving at constant velocity.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
Yes. An object moving in a straight line at constant speed has constant velocity.
there is no acceleration if the body is moving with constant velocity
Only if the direction is constant and the speed is constant.

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 ... :) :]
