Here is a movie showing how an increase in mass of an object can affect the object`s acceleration.

From the above famous equation you can see that an increase in the mass, m, will reduce the acceleration provided the unbalanced force remains the same.

This is why your car will have a smaller acceleration when it is full of passengers than it would have when empty.

Here are a couple of posters you can download to remind you of what the new National Courses.

Hi physics lovers!
Here is a link to the PhET site on refraction.

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.

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.

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

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.
