One of the most basic things students do in a physics lab is to collect data and use that to build a model. Most of these models come in the form of a mathematical function. But here is the problem.

This video explains how a distance-time graph represents how the distance of an object changes over time. The y-axis represents distance travelled, against time on the x-axis. A horizontal line ...
