speed is the rate of change of distance with respect to time.
velocity is the rate of change of displacement with respect to time.
speed is a scalar quantity.
velocity is a vector quantity.
the actual length covered by a body from initial position to the final position is known as distance.
the shortest length covered by a body from initial position to the final position is called displacement.
distance is a scalar quantity.
displacement is a vector quantity.
the rate of change of increasement of velocity with respect to time is called acceleration.
the rate of change of decreasement of velocity with respect to time is called retardation.
in acceleration a. remains always positive.
in retardation a. is always negative.
