Question

what is the relationship between relative speed and velocity

Answer 1

The concept of Relative Speed is central to most physics. When do we say that a body is in motion? If you are lying perfectly still on the ground, are you in motion or are you at rest? The answer is that if you change your relative position with respect to something, you are in motion. Otherwise, you are in a state of rest.
