    velocity is the rate of the change in the position with respect to time (dx/dt)

    its magnitude is speed but as a vector it also has a direction

    acceleration is the rate of the change in the velocity with respect to time (dv/dt or d^2x/dt^2)

    by calculating the slope between the two points if the coordinates of point 1 are (t1,x1) and point two (t2,x2) then the average velocity is (x2-x1)/(t2-t1)
