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.

Distance-time graphs show distance on the vertical axis and time on the horizontal axis. The gradient of a distance-time graph represents speed because gradient = \( \frac{\text{change in ...

Come to lab (hopefully not late). Most likely listen to a boring (but short) lecture that seems similar to stuff that was also covered in lecture class – but it’s still confusing. Look at some new ...

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.
