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 ...

Real life situations such as travelling over time and across distance can be drawn on a graph. Exact distances and times are plotted on the graph. These are shown as co-ordinates. These points are ...

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.
