One must get the methods of measuring position and time working together if we are to obtain a reliable representation of motion. To that end we have developed a unique system composed of elements ...

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

A horizontal line on a distance-time graph close distance-time graphA graph with distance travelled plotted on the vertical axis against time taken on the horizontal axis. shows that the object is ...

The area under a curve can be estimated by dividing it into triangles, rectangles and trapeziums. If we have a speed-time or velocity-time graph, the distance travelled can be estimated by finding the ...
