A Physlab consists of three things. The first is a simulation that you can interact with. The second is text describing a basic principle of physics. The two go hand in hand - the text should help you understand what is being shown in the simulation, and the simulation should help you understand what is being discussed in the text. To test your knowledge there is a third component, the Milestones - these are questions that will let you know whether you understand the material.
|Clicking on a milestone icon will bring up an interactive question so you can test yourself to see if you understand the concepts being discussed.|
|The pen and paper icon will accompany many of the milestones, following up the conceptual question with a numerical question you can work out on paper. In most cases you will need to measure something using the simulation. Answers are given at the end of each Physlab.|
|Although you are strongly encouraged to play with the simulations at all times, the check-mark icon will accompany a hint to guide your interaction with the simulation.|
