when the body in motion covers equal displacement in equal intervals of time.
That means that the velocity doesn't change.
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
In that case, the velocity is said to be constant.
If your velocity is constant, then your acceleration is zero.
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
If the force is constant then this will make the velocity of the object spinning constant as well, and for the velocity to be constant all the forces must be balanced and therefore constant
Yes, speed is the scalar of velocity.
Constant velocity means constant speed in a straight line.
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.
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
"Constant" means that it doesn't change.
constant velocity means the speed and direction are the same.
