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, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
No, it is not possible to go around a curve with constant velocity as velocity is a vector quantity that includes both speed and direction. As you move around a curve, the direction of motion changes, which means the velocity is also changing even if the speed remains constant.
In central force motion, the centripetal force acts perpendicularly to the velocity, causing the direction of the velocity to change but not its magnitude. As a result, the areal velocity (the rate at which the radius vector sweeps out area in a given amount of time) remains constant. This is a consequence of angular momentum conservation in a central force field.
Yes, speed is the scalar of velocity.
Constant velocity means constant speed in a straight line.
Yes, when an object is moving at a constant velocity, it means it is moving with a consistent speed in a straight line. Velocity includes both speed and direction, so if the direction remains constant, the speed must also remain constant.
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.
