What is the defining characteristic of velocity?

• A. It is a scalar quantity
• B. It measures only the speed of an object
• C. It includes both speed and direction
• D. It describes the distance traveled

Answer: (C)

The defining characteristic of velocity is that it includes both speed and direction. Unlike speed, which is only a measure of how fast an object is moving, velocity provides a more comprehensive understanding of an object's motion by specifying the direction in which that speed is applied. For instance, if a car is traveling at 60 miles per hour to the north, its velocity is not just the speed (60 mph) but specifically incorporates the northward direction. This distinction is crucial in physics, as knowing the direction of motion allows for a better understanding of the object's path and can influence how forces interact with the object.
