State the mathematical relationship between average velocity, displacement, and time interval.

Let u = initial velocity, v = final velocity, s = displacement, andt = time.[tex]\text{Average velocity } = \frac{u+v}{2}[/tex]The equation that links [tex] \frac{u+v}{2} [/tex], s and t is one of the five equations of motion that apply for a constant acceleration:[tex]s = \frac{u+v}{2}t [/tex]
