What is the unit of velocity?
Correct Answer:
Meters per second
Explanation:
The unit of velocity is meters per second. This unit describes how far an object travels (in meters) over a certain period of time (in seconds), effectively conveying the rate of movement. Velocity specifically represents both the speed and direction of an object’s motion, making this unit crucial for understanding motion in physics and aviation contexts. Other options represent different physical quantities. For instance, kilograms per square meter (kg/m²) is a unit related to surface density. Joules measure energy, and Newtons measure force. These units serve distinct purposes and cannot be used interchangeably with velocity. Therefore, identifying meters per second as the correct unit underscores the importance of precision in defining physical concepts.
