Navy sponsored Chevy Monte Carlo NASCAR leads a pack into turn four at California Speedway. As a change of direction occurs while the racing cars turn on the curved track, their velocity is not constant. For example, “5 metres per second” is a scalar, whereas “5 metres per second east” is a vector. Constant direction constrains the object to motion in a straight path thus, a constant velocity means motion in a straight line at a constant speed. For example, a car moving at a constant 20 kilometres per hour in a circular path has a constant speed, but does not have a constant velocity because its direction changes. Hence, the car is considered to be undergoing an acceleration.

The big difference can be noticed when we consider movement around a circle. The average velocity is always less than or equal to the average speed of an object. This can be seen by realizing that while distance is always strictly increasing, displacement can increase or decrease in magnitude as well as change direction. Example of a velocity vs. From this derivative equation, in the one-dimensional case it can be seen that the area under a velocity vs. Although the concept of an instantaneous velocity might at first seem counter-intuitive, it may be thought of as the velocity that the object would continue to travel at if it stopped accelerating at that moment. Neither is true for special relativity.
