For example, if it is given that a car is travelling and it accelerates from its resting position with an acceleration of 6.5 m/s2 for a time span of 8 seconds, reaching a final velocity of 42 m/s, east and a displacement of 120 m, then the motion of this car is fully described. Now, if anyone of this information was not provided, we could have easily calculated it with the help of kinematics equations.
