Average acceleration = change in velocity รท change in time
Formula: a_avg = (v_f – v_i) / (t_f – t_i)
Identify the initial velocity
Identify the final velocity
Identify the initial time
Identify the final time
Subtract initial velocity from final velocity
Subtract initial time from final time
Divide the change in velocity by the change in time
Use units of m/sยฒ if velocity is in m/s and time is in seconds
