It is an worked example for teacher to teach the ideas: "gradient of v-t graph represents acceleration" Teacher can print it as a worksheet for students to do so as to assess their understanding on this concept.

This simulation is ideal for teachers to show students the movement of the particles in a medium when a vibrating source disturbs the particles in the medium. It is especially useful when teacher explain the idea that "energy is transferred in a direction perpendicular to the direction of vibration of the particles."

Worked example of a step-by-step guide to find the resultant force of two component forces using graphical (parallelogram) method.

Use some simple animation to illustrate to students how the size (magnitude) of resultant force of two component forces depends on the angle between the two component forces. The size of the resultant force ranges from zero to the arithmetic sum of the sizes of the two component forces.
