Answer:

Explanation:
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).
Constant Velocity
An object with a constant velocity does not change in speed or direction. The only objects that qualify as moving at a constant velocity are those that move in a straight line at a steady speed. An object outside a solar system, in interstellar space, that is not under the influence of outside forces might be described as an object that moves with a constant velocity.
Changing Velocity
Objects with changing velocity exhibit a change in speed or direction over a period of time. Changes in the velocity of objects are measured as acceleration. Objects with a constant speed and a changing direction are also accelerating. Comets and asteroids within the solar system are examples of objects with changing velocity since their speed or direction is influenced by gravity.
