This is the third part of a mini-series looking at motion and here we’ll be considering different ways to measure speed as well as some common sources of error. In theory, speed is easy; we just need a distance (measured using a ruler, for example) and a time (probably measured using a stopwatch but ideally … Continue reading Measuring Speed
Experimental data
One of the most important skills that is required for success in physics is the ability to handle experimental data in an appropriate way. This includes everything from correct use of units and equations to identifying anomalies, finding averages and recording calculations with the proper number of significant figures. All of these skills are tested … Continue reading Experimental data
