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 simple simulation of CRO (Cathode Ray Oscilloscope) can help students understand better the effect of adjusting gain setting and time-base setting of the CRO on the waveform (traces) shown on the screen.
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."
