Please mark me brainliest:
Speed:
It has only magnitue, so, it is a scalar quantity
It cannot be negative, since it's formula is
Velocity:
It has both magnitude and direction, so, it is a vector quantity
Velocity can be negative, plus, if the displacement is zero (when an object moves from a point and returns to the same point with the same path) then velocity will also be zero
