In an introductory sharing for the use of GeoGebra to my colleagues, I have prepared a simple template for them to try their hands at animations of points and other elements. You can try the same too. Create a moving… Continue Reading
Through this GeoGebra app, students can observe how the gradient of the displacement-time graph gives the instantaneous velocity and how the area under the velocity-time graph gives the change in displacement. In the GeoGebra app below, you will see a… Continue Reading
This GeoGebra app allows students to observe the difference between instantaneous and average velocity from a graphical perspective.
The following GeoGebra app simulates the force vectors on an object in uniform vertical circular motion. A real world example of this would be the forces acting on a cabin in a ferris wheel.
This is a simulation that shows the vectors of forces acting on an object rolling in a vertical loop, assuming negligible friction. To complete the loop, the initial velocity must be sufficiently high so that contact between the object and… Continue Reading
This GeoGebra app is a 3-D visualisation tool of the force vectors acting on an aircraft turning with uniform circular motion in a horizontal plane. I prepared this in advance as I will be lecturing on this JC1 topic next… Continue Reading
This app is used to demonstrate how a spherical object with a finite volume immersed in a fluid experiences an upthrust due to the differences in pressure around it. Given that the centre of mass remains in the same position… Continue Reading
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… Continue Reading
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… Continue Reading
