IB Physics Topic 1 Videos (SL & HL)

Topic 1: Measurements & Data

This page contains all of our IB physics topic 1 videos created for topic 1. They cover the IB physics measurements and data processing content from the IB physics course. The videos cover all the sub-topics, including a focus on: units, scientific notation, significant figures, random error, systematic error, uncertainties, vectors & scalar quantities, and vectors.

Our IB physics measurements videos introduce the topic 1 syllabus knowledge required for the IB physics topic 1 questions in the exam!

IB Physics Topic 1 Videos

Video 1

Units, Significant Figures & Scientific Notation
Units & Notation

This video begins by exploring fundamental and derived units, including examples. It then proceeds to distinguish scalar units and vector units. Then, the rules of significant figures are discussed with examples. The video then introduces scientific notation and how to apply significant figures to these, before ending on the appropriate prefixes for units based on the scientific notation.

This video looks at the basic properties of measurements. To finish, it explores using scientific notation to express numbers.

Video 2

Accuracy & Precision, Uncertainty, Errors, & Graphing
Accuracy, Precision & Graphing

This video introduces the concepts of accuracy and precision when measuring data. This is followed by discussing absolute and percentage uncertainty. Next, the two types of errors: systematic and random, are defined and distinguished. Lastly, the video covers graphs and how to determine the slope, x-intercept, y-intercept, and their uncertainties.

This video looks at the essential properties of data. Then, it covers how to sketch, draw, and analyse graphs.
