Speed

Speed = Distance
              ------------
              Time

Increasing thr speed increases the distance covered in the same time.

Increasing the speed reduces the amount of time needed to cover the same distance

Velocity

Average Velocity = Displacement
                              ------------------
                              Time

Speed has magnitude only it has a scalular quantity.

Velocity has a magnitude and direction, it is a vector quantity.

Acceleration

Acceleration = change in velocity
                       -----------------------
                       Time taken

If velocity is constant, the change in velocity is zero and the acceleration is 0 m.s per second or 0 m/s/s.

If velocity increases by 1 m/s every second, the acceleration is 1 m/s/s.

If velocity increases by 2 m/s every second, the acceleration is 2 m/s/s.

If velocity decreases by 2 m/s every second, the acceleration is -2 m/s/s ; this is often called deceleration.

Calculating motion

v = u + at

Average velocity = (v + u)
                             ----------
                                  2

v2 = u2 + 2as

s = ut + 1 at2
            ---
             2

s = (u + v)
