2014 Extension II Assessment III with Marking Scheme

Here is the last assessment, with the marking scheme included.

2009 HSC, Question 4(b)

Another question on the conical pendulum, this time with a minor variation that has it constrained to the surface of a cone.  The message is still the same - set your question up clearly, finding components in the horizontal  and vertical (or in some cases, radially and tangentially), the use Newton's Second Law. 
If you can successfully find the components, most of the subsequent parts following relatively easily.

2014 Sydney Morning Herald HSC Study Guide

As they have been doing for a good number of years, the Sydney Morning Herald have again published their HSC Study Guide.  Here is the link for this years guide.  It contains a lot of very useful advice.

2006 HSC - The Conical Pendulum

Another question on the conical pendulum.  Notice how they are similar?

1999 HSC - The Conical Pendulum

Questions on conical pendulums are quite common in the HSC, albeit with minor variations.  Most start with having you finding components of the forces acting on the bob, so this is something you need to be able to do.

Circular Motion

As we continue our discussion of Mechanics, here are some notes on circular motion. 
Just remember that the centripetal acceleration is always directed towards the centre.

Resisted Motion Worksheet

Here are some resisted motion questions.  I am not sure where they came from, as they were hand written.  If the original owner sees these here and contacts me, I will acknowledge them on the blog!
