A-level Physics Measurements and Errors

teachingisgood is proud to present this presentation which goes over all the key information needed for practical skills in A-level Physics. This presentation explains working with and deriving SI units, definitions and explanations of uncertainties and the mathematics behind Physics.

As a whole, this presentation includes:

• SI units
• Significant figures
• Base units
• Derived units
• Unit prefixes
• Measurements of energy
• Converting between J, eV and, kWh
• Accuracy and precision
• Reproducibility and repeatability
• Errors and uncertainty
• Random and systematic uncertainty
• Ways to reduce the different errors in practicals
• Absolute uncertainty and percentage uncertainty
• Reducing percentage uncertainty
• Combining uncertainties
• Graphing uncertainties and gradients
• Micrometers and calipers
• Approximations
• Estimating masses

This presentation also includes loads of practice questions to truly test your knowledge of these topics and to gain a full understanding of how the mathematics and graphing works. The are lots of animations and graphics as well to help make the steps you should take in these processes clearer.
