Each line segment of a distance-time graph represents one part of a journey. A distance-time graph, sometimes referred to as a travel graph, is a way of representing a journey. It is helpful to have ...

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...

Planar graph algorithms constitute a pivotal area in theoretical computer science, addressing problems where graphs can be drawn on a plane without edge crossings. Among the myriad challenges in this ...

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.

NASA has released an interactive online tool that enables students to simultaneously visualize and manipulate three linked representations of a distance-rate-time problem. The side-by-side tool format ...

Abstract.In this paper, we determine the degree distance of G× K r 0 , r 1 ,..., r n−1 and G⊠ K r 0 , r 1 ,..., r n−1 , where × and ⊠ denote the tensor product and strong product of graphs, ...
