Lesson Plan for Online Lecture on Forces

I am using this post as a way to document my brief plans for tomorrow’s Google Meet lecture with the LOA students as well as to park the links to the resources and tools that I intend to use for… Continue Reading

Free-Body Diagrams in Two-Body Motion

Students are often confused about the forces in drawing free-body diagrams, especially so when they have to consider the different parts of multiple bodies in motion. Two-Body Motion Let’s consider the case of a two-body problem, where, a force F is applied… Continue Reading

This simulation traces the flux linkage and corresponding emf generated by a rectangular coil rotating along an axis perpendicular to a uniform magnetic field. One is able to modify the angular frequency to see the effect on the frequency and… Continue Reading

Simulation: How emf is generated

This simulation is really more of an animation that allows students to apply Fleming’s left hand rule on a line of electrons along a conductor cutting a magnetic field in order to appreciate how emf is generated.

DeLight Version 2

I modified “DeLight”, the board game that I designed a few years back into a worksheet version (for small groups) as well as a powerpoint version (that teacher can facilitate as a class activity, pitting half the class against another).… Continue Reading

Phase Difference Simulation

I created this simulation for use later this semester with my IP4 classes, to illustrate the concept of phase difference between two oscillating particles.

Using a mobile phone in a petrol station.

So it’s safe to use a mobile phone in a petrol station. But not wearing nylon. For more on this, read the Straits Times article : http://www.straitstimes.com/asia/se-asia/use-of-mobile-phones-at-petrol-stations-do-not-cause-fires-experts

Explanation for Water Bending with Static Electricity

It’s interesting to note the differing views regarding the explanation for how a thin stream of water can get bent when a charged object is placed near it. It started with these two videos from Veritasium: https://www.youtube.com/watch?v=1Xp_imnO6WE This video then… Continue Reading

Simulation for Gravitational Field Strength and Potential

This simulation allows students to observe the variation of gravitational field strength and potential between two masses. Field strength is shown as vectors whereas potential is shown as scalar values on a plot. The resultant field strength and potential are… Continue Reading

Falling with Parachute

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.
