This Geogebra app allows students to explore how the position of the centre of gravity as well as the width of its base affect the stability of an object.
This animation is made using Geogebra. It shows the instantaneous velocity and displacement vectors of a particle undergoing simple harmonic motion while tracing its position on the velocity-displacement graph. It is meant to help student understand why the graph is an ellipse.
Try using the values in this simulation to find the velocity of this wave! Let me have your answer in the comment section!
Update on 21 August 2018: The latest iteration of this App is found here:
I am once again exploring the use of Geogebra to create simulations for Physics. This is what I managed to put together. It serves to help students visualise how a particle in a transverse wave moves. The slider allows the user to pick any particle along the horizontal direction of the wave.
