@All.

The definition of speed and velocity are same except that speed doesn't have any direction whereas velocity has. So, speed is scalar and velocity is a vector quantity.

Velocity means (speed+direction).

Speed-scalar.

Velocity- vector.

We mention the speed in distance unit per time unit ex: km/ hr (or) m/ sec (or) some other else.

We mention the velocity in the same kind. Then how we identify it is scalar or vector? Anybody clear my doubt.
