Relative Velocity Simulation
River Velocity: 0 m/s Animate Boat In yet another demonstration of ChatGPT 4o's capabilities, I generated the above simulation app without writing a single line of code myself:...
Vector Addition
I made some refinement to an applet created last year to demonstrate how vector addition can be done either using vector triangle or parallelogram methods. To access directly in...
Unit Conversion Self-Practice
This new applet is designed for students to practise conversion of common units used in physics on their own. There is a checking algorithm within, which might need some...
Standard Form and Prefixes
This little applet is designed to allow students to change the order of magnitude and to use any common prefix to observe how the physical quantities are being written. To view...
Micrometer Screw Gauge - Self-Practice GeoGebra Applet
After completing the vernier calipers applet, I simply had to do a similar one for the micrometer. However, this was a lot more complex as the thimble's numbers are supposed to be...
Vernier Calipers - Self-Practice GeoGebra Applet
The aim of this applet is to help students who just learnt about zero errors in vernier calipers to get some practice of their own. Students just have to key in their answer into...
Who Wants to be a Base Unit?
This is a game that I play with my classes in the beginning of the course after they have attended the first lecture on base units. It serves as an ice-breaker since this is...
