The distance travelled by an object moving at constant speed can be calculated using the equation: ...

Physics can feel inscrutable to students; this lesson helps them understand a graphing problem by analyzing their own ...

One of the most basic things students do in a physics lab is to collect data and use that to build a model. Most of these models come in the form of a mathematical function. But here is the problem.

It is not only moving objects whose speed can vary. The speed of the wind and the speed of sound also vary. A typical value for the speed of sound in air is about 330 m/s.
