greater change in momentum
or
greater mass of air (each second)

I'll probably post tomorrow but for now, good luck everyone! :smile: let's hope it's not as bad as Biology eh.

Sent you a PM. :biggrin:
Absolutely ****ting bricks! I hate physics.
Also, it's in the afternoon which I've never experience but we have double physics before it so i can brush up last minute...
Lost so many marks on silly mistakes like forgetting units:s-smilie:
Lets hope it's easy, unlike biology
I'm so worried about this exam.

I totally haven't revised properly because I have been so worried about my Biology Unit 3 retake last week along with the Chemistry Unit 2 which my mind went blank in the empirical formula question -_-. I also forgot to print off some past papers last week, so I haven't been able to do any of them. xD

Anyway, I'm just going through the specification notes, which are the best way I think to revise last minute. :P
Can anybody explain momentum to me? Confused with all of it.
Lets compare answers everyone. Got a full tray of chocolates - let the depression begin -.-

Omg omg omg how did you guys find it?? It started off so good and then it just got worse and worse :'( some of the questions were soo confusing! Like those two pages on rutherfords crappy experiment :/ and the change in momentum question!! Omg what did you guys put?

And the graph omg I wanted to kill someone!

Come on then what were the answers!
On the graph i sketched 3 different lines and crossed them out, hopefully my fourth was right. :L

I got 98 then 9.6 then 9600

It ended all the way at the top right corner. It wasn't a straight line it curved.

The line went through the point which was linked with the first question on that page, and where the line finished was given in the question - you had to read it and analyse it.

Who else wanted to cry when they saw the 3 mark question where you had to explain the path taken by the alpha particle?

I got 9.6 too I think. Can you remember the figures you put into the calculator?
Should refresh my brain.

What was the answer for the catching question?

i did 0.16x30 = 4.8
then 0.16x-30 = - 4.8
then worked out the difference :smile:

did you get 4m/s squared for the velocity time graph
