Final answer:
The change in position divided by the change in time is known as the average velocity, which can be calculated using Δx / Δt and visualized on a position vs. time graph.
Step-by-step explanation:
The change in position divided by the change in time defines average velocity. Average velocity is a vector quantity described by both magnitude and direction, defined mathematically as Δx / Δt (where Δx is the displacement and Δt is the time interval). When calculating average velocity, ensure that all distances and times are converted to meters and seconds for consistency. This concept can be visualized on a position vs. time graph, where the slope of the line indicates the object's velocity over time. Moreover, if an object has constant acceleration, the acceleration remains unchanged over time.
If we have a position vs. time graph, it can be used to describe the change in velocity over time. The gradient or slope of the graph represents the average velocity or change in position divided by the change in time.
An example of average velocity calculation would be: If an object starts at position x0 and moves to position xf in time interval t, the average velocity is (xf - x0) / t.
