Physics paper 31

[Wolfgangs]

So, how was the paper?

Did you get a graph with positive or negative gradient?

 

[malooky sugarcube]

i got a negative gradient

 

[omaaaar]

Negative gradient

 

[omaaaar]

Paper was overall easy but that part was just rubbish were we had too make the angle between the two strings 90

 

[David Black]

Negative gradient

how did you get the mass then?

[omaaaar]

how did you get the mass then?

Don't really remember how I found it

 

[David Black]

Don't really remember how I found it

because a negative gradient will give a negative mass

 

[Wolfgangs]

Well, everyone results vary it seems XP. I got a positive gradient idk why, and I checked around two times.

guys was the experimant both mechanical?

 

[Ahmedlool]

experiment ****

 

[Ahmedlool]

or was it electrical and mechanical as people have told me it was that

 

[Wolfgangs]

Mechanical only, and was there a relation between the f and x? There was no relation right, as k is quite different for both

 

[Ahmedlool]

what about paper 32? is it gonna be mechanical only?

I got a negative gradient of -0.03 and a y-intercept of +10.2 something. I have one question - there must be variations in values for all candidates' answers, so on what basis do the examiners mark our answers? Do they grade us on basis of our method or whether our answers lie within the range they determine?

 

[Wolfgangs]

What about the relation in Q2? I got a big difference between the two constants k, so they are not related, right?

 

[Wolfgangs]

What about the constants k, what did you guys get? Did the time increase or decrease as you changed?

 

[Autumngirl]

What about the constants k, what did you guys get? Did the time increase or decrease as you changed?

Time decreased as x decreased. My results supported the equation as I got only 11% difference between my two values of k.
