What to do during the holiday?

holiday homework:)

Regret your decision for choosing the subject































But seriously (not the above wasn't serious, because it was), do some light reading for Unit 3. It's fairly dull imo, but it'll help. Go over Unit 1/2 concepts such as Motion and Electric circuits too.

edit: downvotes LOL, thanks

Upvoted you pi, just because I do appreciate your Physics jokes, they do have a substance of truth behind them sometimes

Anyways, I agree with pi, the main stuff would be motion, so make sure you're up to scratch with all of motion from year 11, especially the equations of motion for constant acceleration as well as Newton's three laws, stuff such as momentum and energy, projectile motion...etc. are important as well, you'll see that there's not that much new stuff in Unit 3, there's just circular motion (and associated things such as planetary motion) added, all the other stuff is just an expansion of stuff done in Year 11.

Electronics - I would say it's a bit too early to get into, but defs make sure you're all good with motion first, I'd suggest actually starting the Year 12 course for Motion before even touching electronics because they're separate and it'll be better to revise electronics before you get into that.

Anyways, defs get your books and stuff ready as well, so know what textbook your school is using and what detailed studies you're going to do, grab a few study guides, I'd suggest the ATARNotes Physics Exam Study Guide, which will be out soon. On top of that, just enjoy your break and remember not to overwork yourself, physics isn't a difficult subject if you keep on top of things and spend time trying to get the better of the hard concepts.

Moderator action: removed real name, sorry for the inconvenience

Thanks guys, but since unit three is an extension to unit 1&2 stuff do you recommend finishing the unit 3 course during the holidays or just read and understand the concept?

Depends if you understood the concepts in Units 1/2 well. If not, I'd revisit those. If so, there's no need and you can jump right into the relevant parts of Unit 3.

I never advocate finishing a whole course during the summer holidays - the most I would recommend would be to do Motion over the holidays, but make sure you know the basics of everything.

Especially now that there's no mid-year exam, there's no real rush to finish the course early, just take it slow and easy and spread out the time you're spending on the subject. Physics isn't a time consuming subject, nor is it hard, you just need to have a good understanding of the basic concepts and you'll be fine.

btw how would I study if i got the worst textbook (jarcada one)？:/

For the original question, I would recommend going through the MIT Open Course-ware Physics course, or/and you can go through some of the Khan Academy Series in Physics, particularly Mechanics stuff. If you are short with available time to spend then I would recommend going through the highlights for high schools stuff done by MIT. Basically it is just clips posted from the first two links below. Additionally, I suggest starting to write a notebook for the 'basics' for motion (or whatever section your school is doing first) and that you can build upon for the rest of the year and can be use as revision. Another resource is hyper physics which is nicely laid and can be used as a easy way to introduce you to the main concepts. You can also go through some of the other websites located in the physic resources thread. Hopefully this is helpful

Simple: You buy another textbook. I recommend Nelson

noooo

Hey guys I am having trouble understanding this explanation :/

The question was A footballer crashes into the fence and stops completely. What has happened to his momentum? Has it been conserved?

The answer was His momentum was transferred to the Earth via fence.

but, I thought that only vertical forces transfer to earth, wouldn't his horizontal force make the fence move?

[Jaswinder]

his horizontal force would move the fence slightly, however since the fence is connected to the Earth, most of his momentum would transfer to the ground.

My physics teacher said (She's great I love her)
Nelson had the most basic questions and explanations,
Jacaranda had the best theory/explanations
And Heinemann has good questions (and lots of difficult ones!)

We use the heinemann textbook
And I'm going to get the jacaranda pdf from the school library once school starts again.
