❉ Speed of a body is the distance travelled by it in per unit time.

❉ Speed is SCALAR quantity.

❉ Speed never be negative.

❉ Speed = Distance/time.

❉ For example: The expression 50 Km/hr is speed as it has only magnitude.

{\bf{\red{\underline{2).\;Velocity:}}}}

❉ Distance travelled by a body per unit time in a GIVEN DIRECTION.

❉ It is vector quantity.

❉ Velocity can be zero.

❉ Velocity = Displacement / time.

❉ For example : The expression 50 km/hr towards NORTH is velocity as it has both magnitude as WELL as direction.
