Figure 8 A card leading to an animated example of a more complex elevator motion. Some example graphs of v and a against s are presented both as static graphs, and in the simulation software. In the latter it is possible to also view the graphs in their previous form as functions of time, and to animate as before. Finally, the book-like material for rectilinear motion prepares the student for the next topic, curvilinear motion, by pointing out that concepts in rectilinear motion can be applied to the tangential component of motion along an arbitrary curved path in space. Figure 10 First contact with the curvilinear motion simulation software.
Students can ask to predict a particular graph or graphs, or can ask for a more random problem.
A student attempting to predict and sketch the shape of one graph based on another. The sketched graph can be edited as many times as the student wishes. Then they can request feedback about their attempt by clicking on the 'done' button.
