### Velocity and speed : the difference

In this video I give a more rigorous explanation regarding the definition of velocity. This is to build on my tentative definition of "The rate of change of distance with respect to time". I explain this using these two videos because I feel it is easier to introduce a new concept (acceleration) when known concepts (speed and not velocity ) are used. So finally I define: "Velocity is the rate of change of displacement with respect to time" "Acceleration is the rate of change of velocity with respect to time"
