The formula for velocity in physics is derived from the relationship between distance traveled and the time it takes to travel that distance. Velocity is defined as the rate of change of position and is typically expressed as distance divided by time. This means that if you know how far an object has traveled and how long it took, you can determine its velocity.

This relationship highlights that velocity has both magnitude and direction, making it a vector quantity. For example, if a car travels 100 meters in 5 seconds, its velocity would be 20 meters per second in the direction of travel. Understanding this fundamental concept is essential in physics, as it lays the groundwork for further exploration of motion and dynamics.

Other options provided pertain to different concepts in physics: mass times acceleration relates to Newton's second law of motion (force), force divided by area pertains to pressure, and work divided by time describes power. Each of these equations serves a unique purpose in physics, but they do not define velocity.
