re: HSC Physics Marathon Archive

any chance of being ever asked to talk about more than one scientist for space?

re: HSC Physics Marathon Archive

Shouldn't be, since the syllabus dot point is:

• identify data sources, gather, analyse
and present information on the
contribution of one of the following to
the development of space exploration:
Tsiolkovsky, Oberth, Goddard,
Esnault-Pelterie, O’Neill or von
Braun

This means you shouldn't need more than one.

(That dot point is on Page 42 of this document: http://www.boardofstudies.nsw.edu.au/syllabus_hsc/pdf_doc/physics_stg6_syl_03.pdf )

Couldn't they ask you any one of them?

I don't think so. Look at Q.21 on Page 13 of the HSC Physics paper from 2013: http://www.boardofstudies.nsw.edu.au/hsc_exams/2013/pdf_doc/2013-hsc-physics.pdf

They implied there that you studied just one of the scientists, and they let you choose one.

Is integration used in anywhere in HSC physics course? I have a formula sheet I got from 'DUXcollege' and there is a standard integrals sheet on the formula sheet....

No its not apart of HSC physics as there are many general studets doing Physics.

Thanks, shitted my pants for a sec.

Calculus in HSC Physics, I wish.

Yeh. You gotta differentiate and integrate the effects to society.

Heard they're introducing extension physics courses in 2017

Yea it was in the Draft Writing Briefs posted by BOSTES (http://www.boardofstudies.nsw.edu.a..._doc/physics-st6-draft-writing-brief-2015.pdf - page 24). I would have liked to try the Extension courses, particularly Extension Chemistry and Physics.

same i would have done an extension. and then i would have had an 11th unit (.well 12th unit really as i only dropped EXT1 math after trials)

Hard to see from that document what the extension courses would actually be like (i.e. whether they are real science or just more of the same as now).

There are 3 options currently being weighed up by BoS. One of them involves the introduction of extension physics and chem.

Still just talks though. Quite a bit of talk about the level of mathematics wanted in it, but I still don't see any calculus being added

Implementation to start in 2019, not 2017.

Fizzy post up some good questions in preparation for the physics exam

re: HSC Physics Marathon Archive

How did Einstein’s theory of special relativity and his explanation of the photoelectric effect lead to the reconceptualisation of the model of light? (6 Marks, from 2008 HSC Physics paper)

Fizzy had a great breakdown of this question

So, there are really 2 parts to this question:

1: How did ESTOR lead to reconceptualization of theory of light


Think About:

- Define Einstein's ESTOR in terms of his 2 postulates
- Speed of light before being relative and distance/time being absolute (Newtonian)
- Speed of light after being constant and distance/time being relative

2. How did his explanation of PE Effect lead to reconceptualization


Think About:

- Describe PE Effect
- Theory of light before being waves (Unable to explain threshold frequency, why intensity does not impact Ek of emitted electrons etc..)
- Theory of light after as light having particle properties, then energy of which is defined by E=hf (explains existence of threshold frequency and why intensity of light has no impact of Ek of electrons etc..)

Then just make a concluding statement showing the model before and after and how ESTOR and his explanation of PE Effect caused changes in the model

What are these two postulates:

Is this one?:
1) Since the speed of light is constant in all frames of reference then space and time become relative ---> leading to mass dilation, time dilation, length contraction

re: HSC Physics Marathon Archive

1. First postulate (principle of relativity)

The laws by which the states of physical systems undergo change are not affected, whether these changes of state be referred to the one or the other of two systems of coordinates in uniform translatory motion. OR: The laws of physics are the same in all inertial frames of reference.
2. Second postulate (invariance of c)

As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body. OR: The speed of light in free space has the same value c in all inertial frames of reference.
