Module 1 – Development of practical skills in physics

Question 1

Describe two examples of methods to reduce uncertainty.

Answer 1

• Electronic data loggers are more accurate, quick and reliable than manual logging as they can take multiple readings per second and present the data as a graph or table in real-time.
• §Cameras can be used to take photos in experiments that happen too quickly to read a scale, use a camera to take a photo burst as the experiment happens and then read the scale from the photos afterwards, if the time each photo is taken is known then properties such as velocity can be calculated.
