The following simulation allows users to observe the effect of air resistance on a parachutist before and after he opens his parachute. Try to open the parachute when the man first reaches terminal velocity and observe the changes in velocity.
This simulation allows students to observe the variation of the normal contact force N acting on a box placed on a frictionless slope with the angle of inclination of the slope changing. It also allows them to see how the… Continue Reading
In this simulation, students can observe the variation of the normal contact force (N) and its effect on acceleration and velocity as an elevator moves upward. Questions for students to work on can include: Express the acceleration as a function of… Continue Reading
I’ve created this simulation to demonstrate the effect of an internal resistance due to a cell on the potential difference and current of an external load. One can also vary the internal resistance and external resistance to observe the maximum… Continue Reading
My third simulation in as many days. This time round, I created some png files for electrical circuit components that can be used for future simulations. I also figured out how to add text in line with a variable in… Continue Reading
Continuing the course on Easy Java Simulation, I did this simple simulation on the Potentiometer, which allows students to first predict, and then verify the position of a jockey to achieve null deflection of a galvanometer. Click on the image… Continue Reading
This is a simulation done from scratch after attending a crash course on EJSS. It displays the velocity and acceleration vectors as an object is projected vertically upward with a uniform downward acceleration. The initial upward velocity can be altered… Continue Reading
I was reading up on tides this morning as I have to relieve a colleague’s IP2 class on forces, when I stumbled upon this video. It explains tides in a way that differs from most textbooks that clarified for me why… Continue Reading
I bought a simple beta Stirling engine online at dx.com recently and it came in the mail today. It works well with a cup of hot water placed under it, although it might take a little push to get it started… Continue Reading
A very good explanation of standing waves on Chladni plates. Watch out for the 3-Dimensional standing wave at 3’11”.
