What best describes the motion of an object experiencing a constant velocity?

An object experiencing constant velocity is defined as moving at a steady speed in a straight line. This means that there are no changes in either its speed or direction over time. When an object maintains a constant velocity, it will cover equal distances in equal intervals of time without any variation in its motion characteristics.

In this context, since velocity is a vector quantity that includes both speed and direction, any variation in either component would indicate that the object is not maintaining a constant velocity. Thus, steady speed combined with a straight-line trajectory perfectly aligns with the definition of constant velocity. This concept is fundamental in physics, particularly in understanding motion dynamics.
