Question

why speed can never be negative?​

Answer 1

Answer:

No speed can never be negative , since it is a scalar quantity and does not have direction. On the other hand velocity can be negative because of the direction component making it a vector quantity. Distance can never be zero or negative for a moving body. This is the reason why speed is not negative.
