Personalities in Physics

In HSC Physics you have to learn about at the minimum

Space - von braun -link
I2I - Planck and Einstein - link - video

Exciting Jobs in Aerospace!

Imagine space!

Imagine going there, the adventure!

Imagine finding a job that takes you on a thrilling mission!

The reality is working through job applications and getting the team together.

See who NASA is looking for .....

"Jobs In Aerospace - Space FlightThe National Aeronautics and Space Administration (NASA) is the central federal agency associated with U.S. space exploration. NASA conducts its work in four principal organizations, called mission directorates:

• Aeronautics
 pioneers and proves new flight technologies that improve our ability to explore space while also having practical applications on Earth.

• Exploration Systems
 develops new capabilities for affordable and sustainable human and robotic exploration.

• Science
 explores the Earth, moon, the other planets in our solar system, and beyond - charting the best routes of discovery while reaping the benefits of Earth and space exploration for society.

• Space Operations
 provides key enabling technologies for much of the rest of NASA through the space shuttle, international space station, and flight support.

Jobs In Aerospace - Going ForwardNASA's vision for future space exploration includes safely returning the space shuttle to flight, completing the International Space Station, returning astronauts to the moon, continuing exploration of Mars and the Solar System, to name a few."
from http://www.jobsaerospace.com/Jobs-In-Aerospace-Space-Flight.html

You are to write your job application for first round selection.  You will be in a team that visits three planets.

For your application you need:

Page 1: Title + You will sell your personal qualities, and skills you have gained after graduating and working in industry. (You are now 25!) 

Page 2: Because the Employer is looking for someone who can think strategically and scientifically, you will demonstrate this by outlining a mission,route, type of spacecraft with objectives.

Page 3: Due to the nature of missions you have to show you understand the requirements of everyone's job by discussing (2 - 4 sentences on each)

a) commander

b) space risk specialist (radiation, depressurization, object impact)

c) space medicine specialist

d) interplanetary navigator (fuel, orbit considerations)

e) planetary science specialist

f) media reporter

h) team analysist (will read applications and select teams)

Page 4+ Add some additional pages headed the Job title and key factors relating to the science of the position. Include any information from the Internet.

Remember you have to plan your time to cover each point.


Share you ideas but add a little extra.


Your applications will be reviewed by an Australian aerospace recruiter and positions offered to further develop you vision.

The most important thing to learn at school....

The most important thing to learn at school is a "Do culture".....



1. Size up the benefit of giving it shot.
2. Set a Goal
3. Make a start
4. Self talk, pilot yourself forward
5. Think strategies, contingencies and develop a campaign narrative.
6. Don't be identified taking on "Can't do that objectives"
7. Think of how tomorrow plays out.
8. Build the mind structure for a new direction.
9. Value intrinsic worth that reshapes the future
10. Provision, Process, Promote among doers.

Now to E.2.a  Electrical Charges, Field and Currents

Textbook Ref Excel 50 - 55 Jacaranda Preliminary Physics - 92 -98

Write down what you know about charges and electricity (Prior Knowledge)

Looking back we can see ancient "brushes" with static electricity, and jolts from electric eels.

One Scientist made the creative jump to invent the concept of charge (electrons) this is a surprisingly good summary Link  Dr Gilbert - he invented the electroscope that shows charge is something that can be put on objects.

Some Youtubes for You:- an electric eel lights up a christmas tree, and a Dr Gilbert style eletroscope - It was Ben Franklin that worked out the - and + aspects







Charged objects can be charge + or -,  like repel, unlike attract.
Objects are shown with the charges + and - , for insulators they are put on and stick, for conductors the move apart from each other

Rub Perspex and rod is Positive
Rub Ebonite and rod is Negative

Click to Run

Note you draw charge as + or - and place it in a circle for a free charge that can move
Note because there is a Force and Distance, FORCEDISTANCE = work
Note Insulators - charge stick, Conductors charge moves inside.
Note Insulators can shuffle charge and become polarized
