Measurements are always uncertain: there is no such thing as a perfectly precise measurement. At the very least, the instrument used will limit the precision of the value but in many cases other factors can introduce even greater variability. It is always the greater of these two numbers (the resolution of the instrument and variability … Continue reading Uncertainties and Error Bars
Velocity-time graphs
We have extended our knowledge of graphs of motion by looking at velocity-time graphs. If you require more information then please read p23 in your CGP Complete Revision and Practice book (GCSE Edexcel Phyics). It is now time for you to test your knowledge and understanding. This is a compulsory homework task that you must … Continue reading Velocity-time graphs
