projectile motion (1 Viewer)

[tacogym27101990]

im just wondering
would it be acceptable to use projectile motion from 3 unit maths to solve physics questions??

because my physics teacher can't explain things well so i never understood projectile motion in physics?

or would calculus be bad in the exam??

thanks

I think that Physics projectile is a lot easier to understand than 3U projectile. =(

no its fine, whatever works, but i wouldnt recommend it. it would waste time, all youre doing is deriving the formulas they give.

i agree but did u do hsc physics i wonder

Because the trajectories are simplified including starting the trajectory only at the origin.
The analysis of projectile motion in Maths Ext. 1 is however more thorough.

i did hsc physics

how you go with first sem physics?

Just slotted myself in for a credit because the final exam was pretty cool compared to all other years.

hmm which uni did you end up going to forbidden?

Well, it would be acceptable.. But it depends on what the markers are actually looking for re: how many marks you will actually recieve for using that approach.

They may be looking for an understanding of when to apply the different projectile motion formulae

Both my maths teacher and physics teacher said this was not allowed. Can't use ext 1 maths way of solving them in phyics, likewise can't use physcis way in maths.

i thought u can. i am pretty sure you can i remember teacher done one in physic in 3 unit maths way mehhh?depends i guess on skool...

but man talk about physics teachers i swear are all physic teacher shit cause the only P teachers i come across are pathetic

 

[Riet]

I didn't realise there was a difference except physics was generally more simplified?

WATCH IT BUDDY!

Us physics teachers are an interesting breed...

 

[melonkitten]

no.

in physics you need to deal with other variables such as air resistance, not just gravity like in 3u

 

[Riet]

Nah, there's no air resistance in HSC physics. Fuck, not even in first year uni physics.
