## Geogebra Simulation of a Potentiometer

Some of the more challenging problems in the topic of electricity in the A-level syllabus are those involving a potentiometer. The solution involves the concept of potential divider and the setup can be used to measure emf or potential difference across a variety of circuits components. Basically, students need to understand the rule - that

## Geogebra Apps for Singapore Physics

I've curated a series of Geogebra apps that are relevant and useful for the instructional objectives under the Singapore-Cambridge GCE 'O' and 'A' level syllabi. Some of these apps were created by myself. If you have any ideas for new Geogebra apps, do let me know in the comments section below and I'll see if

## Box on a Vertical Oscillating Spring - Geogebra App

GeoGebra link: https://www.geogebra.org/m/ev62ku7w Students can explore how varying frequency and amplitude of the vertical oscillation of a platform could cause an object resting on it to temporarily leave the platform (i.e. when normal contact force is zero).

## Geogebra App for Kinematics

As one of the first topics in A-level physics, kinematics introduces JC students to the variation of velocity and displacement with acceleration. Very often, they struggle with the graphical representations of the 3 variables. This Geogebra app allows students to vary acceleration (keeping it to a linear function for simplicity) while observing changes to velocity

## Wavefront

In order to help students visualise a wavefront, a 3-D image is usually used to show the imaginary line joining particles in phase. I created the Geogebra apps below to allow students to change the wavefront and observe it move with time at a constant wave speed. There represent simplified versions of waves on a

## Graphs of a Progressive Wave - Geogebra App

GeoGebra link: https://www.geogebra.org/m/f7faw3r6 This simple Geogebra app allows students to observe the oscillation of a particle perpendicular to the direction of energy transfer.

## Centre of Gravity and Stability - Geogebra App

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.

## Velocity-Displacement Graph of a Simple Harmonic Oscillator - Animation

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.
