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.

Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken. is the rate of change of velocity. It ...

Watch this video to see how a distance-time graph can be used to calculate speed and acceleration. In a distance–time graph, the gradient of the line is equal to the speed of the object. The greater ...
