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.

Each line segment of a distance-time graph represents one part of a journey. A distance-time graph, sometimes referred to as a travel graph, is a way of representing a journey. It is helpful to have ...

The slope or gradient of the line of a distance time graph is equal to the speed of the object. The steeper the line (and the greater the gradient) the faster the object is moving. Gradient = ...
