Physics unit 1 6PH01 discussion :)

Yeah I said something along those lines should be fine! The important thing I think is to fact that the whole line isn't doesnt show direct proportionality

and for the co2 emission i considered as 1 car not 3? ((

 

[svenas]

Where do you think the boundaries will lie for this exam?

53-55 u?

 

[ALevel96]

53-55 u?

Yeah I agree I would say 55 as well.
Although a lotttt of calculation questions therefore many people may slip up.

 

[ALevel96]

What did everyone's vector diagram look like?

 

[cardude456]

w
hat did u get? i got 6MW!

Yh......i got smthin like tht.....although i just left it as watts..not megawatts

 

[ALevel96]

and for the co2 emission i considered as 1 car not 3? ((

Might be that then although it did say for the three cars so hmmm

 

[Herald Grove]

Where do you think the boundaries will lie for this exam?

I think 55-6

 

[svenas]

Might be that then although it did say for the three cars so hmmm

i guess it ll still gv same answer?

 

[jackoo123]

for the co2 question i got 2.something is that correct
?????

 

[Herald Grove]

Exam wasn't that hard but the *TIME! I did the last three questions in just 15min. Skipped all of the parts which required a lot of thinking. I hope I get a B at least. If the grade boundary is around 55 then there is high chance that I might get a B, hopefully.

you

didnt reply to my question? -_-
why did i get a diff answer by using f=ma and then p=f*v?

 

[ALevel96]

Maybe due to the acceleration not being constant ..

 

[jackoo123]

and for the co2 emission i considered as 1 car not 3? ((

the answer was 2.34 or something close

f=ma then f*v is correct...

 

[svenas]

the answer was 2.34 or something close

no i got 0.smthng

 

[ALevel96]

the answer was 2.34 or something close

For the cars travelling at 5 m/s yes it equals that but you haven't subtracted the other value when they travel at 18m/s

 

[abdul aziz123]

f=ma then f*v is correct...

but i got 6MP? IS THAT CORRECT?

 

[jackoo123]

no i got 0.smthng

(0.26*3)*3=2.34kg/km (the distance is 3km, you have 3 cars so you multiply the 0.26*3 (emission for one car) and then you multiply by 3

 

[jackoo123]

but i got 6MP? IS THAT CORRECT?

i think i got the same

 

[svenas]

(0.26*3)*3=2.34kg/km (the distance is 3km, you have 3 cars so you multiply the 0.26*3 (emission for one car) and then you multiply by 3

i didnt multiply by 3 so i ll lose 1 mark? i assumed 1 car
