Kinematic Equations Average velocity is defined as the
total displacement divided by the total elapsed time. It is a vector quantity.

Kinematic EquationsAcceleration is defined as the time
rate of change of velocity. It is a vector quantity.

Kinematic Equations∆ means “ change in”
∆d = df –di
∆t = tf –ti
∆v = vf -vi

Kinematic EquationsFor constant acceleration, the average
velocity for any given interval of time can be found by taking one-half the sum of the initial and final velocities:
