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 peak emf 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.
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). Worksheet: DOWNLOAD Slides: DOWNLOAD The objectives of the game is to reinforce concepts related to
As I was teaching the use of the potential divider equation to my IP4 (Grade 10) students last week, I approached it by teaching the rules first before showing worked examples. Thereafter, as some students remained confused, I merely reverted to explaining the rules. Eventually, I resorted to simplifying the equation by substituting simple numerical
I created this simulation for use later this semester with my IP4 classes, to illustrate the concept of phase difference between two oscillating particles.
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
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: This video then sets out to disprove Veritasium's model of ions being removed from the water stream.
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 shown in red.
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 Weight vector W can be resolved into two components, with the one perpendicular to the
