What does velocity refer to in the context of walking?

Velocity, in the context of walking, specifically refers to the speed at which a person walks, which incorporates both the distance traveled and the time taken to cover that distance. It is a vector quantity, meaning it has both magnitude (how fast) and direction (the path taken). In simple terms, if you know the distance a person has walked and how long it took, you can determine that person's walking speed, which is essentially what velocity measures in this context.

While the number of steps taken in a minute, distance walked in a specific timeframe, and cadence of footsteps are all related to walking, they do not fully capture the concept of velocity as it pertains to speed. Velocity is primarily concerned with how quickly a person is moving, making it the most appropriate answer in this scenario.
