2010 Extension 2 HSC - A question on Banked Tracks

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.

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!

2012 HSC - Resisted Motion

Resisted motion is a relatively common feature of HSC mechanics questions, be they in a straight line, or projectile motion questions.  The important point is to use Newton's Second Law, $$\sum F=m\ddot{x}$$  Make sure you always define you directions at the start!

Extension II Mechanics Syllabus

Here is an interactive form for you to check off each part of the syllabus as we work through mechanics.
There seems to be a lot here, but don't let it put you off!  Most the of mechanics hinges on the ability to write components  of vectors and make sure the signs are correct.
