Intermediate 2 Physics Circuit Practice.

Posted by Mr Mallon on March 10, 2012

This is a fantastic piece of simulation software from PhET which allows you to build electric circuits and study what happens when you change resistance or voltage.

Download the simulation by clicking on the picture.

To get you started why don`t you build this circuit
Investigate:

  1. How the current in the circuit changes when the 8 ohm resistor is doubled
  2. How the voltage will change across the 24 ohm resistor when the 8 ohm resistor is doubled.

Have some fun building more circuits and investigating the the current, voltage and resistance of the circuit.

Gravitational Field Strength! (Int2 and SG fourth year)

Posted by Mr Mallon on February 18, 2012

Hi physics lovers!

The gravitational field strength tells us how much force a planet exerts on each kilogram of mass.

Read the cartoon and see if you can find a link between the mass of an object, its weight and gravitational field strength of the planet.

Here is an interesting poster showing the dose equivalent for various situations.
Dose equivalent is measured in sieverts.

Faster than light neutrino infographic.

Posted by Mr Mallon on December 4, 2011

It is the biggest story in the world of physics. Here is a good infographic to read and impress your science/physics teacher with.

See how scientists caught subatomic particles traveling faster than light in this LiveScience.com infographic.

Nasty Nine Champion 2010-2011 Gavin Grant

Posted by Mr Mallon on December 2, 2011

Every year I run a nasty nine physics revision league. I call it Nasty Nine because there are usually nine questions which are not really nasty but only nasty if you haven`t kept up with your physics study.

All the points are toted up and at the end of the year the student with the most points wins a Nasty Nine mug.

This years winner was Gavin Grant from my Intermediate 2 class. Standing along side him are his colleagues in the class Dylan Sneddon and Harith Malik. Great students.

Flying through space looking down on our planet.

Posted by Mr Mallon on November 15, 2011

A super time lapse film of the International Space Station as it flies over the planet.
Look out for the aurora. These are the green bands on the edge of the Earth. You can also see lightning storms and big cities lit up at night.
What a joy to see.

Potential and Kinetic Energy Fun!

Posted by Mr Mallon on November 1, 2011

Hi physics lovers! Here is the brilliant PhET simulation which is exactly what we were studying this week in both Intermediate 2 and Standard Grade physics.
Run the simulation like the real loop in lab and study the graph of potential energy and kinetic energy with and without friction.
