Velocity
Speed that is accompanied by direction is called velocity. For example, when a car is moving at 80 km/h going north, you can identify the direction the car is traveling, thus, identifying its velocity. Distance and speed are both called scalar quantities. When quantities deal with both magnitude and direction like displacement and velocity, such quantities are called vector quantities.
There are instances when a car does not travel at constant velocity. The following table shows the changing velocity of a car from the time it started to move until it has covered a distance of 500 m.
Distance covered by a car at different time intervals
Plotting the given data in a graph yields a parabola, inferring that the car moves at a faster rate.
