Technology: notes and practice questions
Summary
- This topic outlines the essential technology skills for collecting and processing data in physics investigations.
- Skills include using sensors, identifying and extracting data from databases, and generating data from models and simulations.
- Image analysis and video analysis of motion are used for data collection.
- Spreadsheets are used to manipulate data and represent it in graphical form.
- Computer modelling is used for data processing.
How it is examined
Weakly examined in the written papers compared with T.1 and T.3, which is a consequence of it being mostly a laboratory skill assessed through internal assessment. Where it does appear in Paper 1B it is as a sentence in the stem ("a datalogger records the temperature every 0.1 s") that sets up an uncertainty or resolution argument later in the question. Do not generate a written question that requires operating software.
Key ideas
- Apply technology to collect data. Use sensors. Identify and extract data from databases. Generate data from models and simulations. Carry out image analysis and video analysis of motion.
- Apply technology to process data. Use spreadsheets to manipulate data. Represent data in a graphical form. Use computer modelling.

Where marks are lost
- Stopping one step short of the conclusion. Two numbers and no sentence is two marks out of three.
- Answering a procedure question with a platitude.
- Losing precision in Paper 1B. Uniquely to this paper, quoting the right number badly loses marks.
