Measurements are always subject to some uncertainty. The minimum uncertainty is set by the resolution of the device used but repeated measurements may reveal a range of readings, which is more significant than the instrument resolution when determining uncertainty. In A-level Physics calculations, uncertainties are combined using two simple rules; If the calculation involves adding … Continue reading How to Combine Uncertainties
How high does a spring toy jump?
Determining a spring toy’s jump height is a useful exercise in the application of physics, not only in terms of this specific example but also in highlighting contrasting approaches to answering any sort of physics question. As is so often the case, there are two possible starting points; the first is theoretical whereas the second … Continue reading How high does a spring toy jump?
