Question for people who use Heinemann Textbook (3+4)

[VCE247]

Do any of you find that for some answers, the answers have been rounded off randomly?
like the answer could be 3.2 x 10^6 m but they have 3.0 x 10^6
am i doing something wrong with my calculations or should i just ignore minor differences like this?

Just do what you do, they have some pretty bad sig fig use

[Aurelian]

I find this as well, and just ignore those minor differences... They don't seem to have very good sig fig usage as Rohitpi said. I think my teacher said that to our class at some point as well :3

Heinemann is always one step behind, the textbook still takes gravity as 9.8

I think that's more being forward.

Agreed; I think it's pretty silly for VCAA to make gravity 10... not that I'm complaining of course; it makes calculations nicer

VCAA takes it as 10, and the book is for vce units 3/4 students so it is not being forward, it is being behind and not updating it.

He means not in the sense of being helpful to study scores in physics but rather forward in the sense of being more true to how things actually are in the world, rather than remaining content to exist within the boundaries of VCAA land.

I understand what he/she means. Actually a textbook should be content with the boundaries of 'VCAA land,' and should try as much as possible to not trangress those boundaries, so students do not get confused. Essentially heinemann is behind in the sense that they cannot keep up to date with the VCAA physics study structure.

Yeah they do that a lot, even in the teacher worked solutions I've seen that they have the same thing there.

[Bozo]

Do any of you have the teachers CD to this textbook?

The books should follow the VCAA! Yer there are a few mistakes...And the rounding is kak
