In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

The questions in this quiz are suitable for GCSE physics students studying motion in a straight line, velocity and acceleration, distance-time graphs, velocity-time graphs and velocity, acceleration ...

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.
