WebFor example, a person standing up from a chair or a plane taking off from a runway. In these cases, there is a clear change from zero velocity to non-zero velocity even though the object starts out at rest. This implies that there must be a moment where the object's acceleration is non-zero although the object remains in the same position. Web24 de ago. de 2024 · Answer: Average velocity is defined as the distance traveled divided by the time lapse. Net displacement can be zero but total distance can’t be zero.
