urgent help in physics design

[sksuriza]

in planning question...do we have to plot an expected graph aswell...or only give the labels for the axisz ...plz urgent!!!

 

[awesome94]

in the planning part where u draw. u draw. no graphs just make sure that apparatus set up is workable...
and in the writing part. where u get marks for the method of analysis. i ussually always draw the graph cuz my teach taught us that way. so yeah, u draw a rough grah, show that it cuts/doesnot cut the y axis. label the axis
but also say: take blah on the x axis and blah2 on the y axis. the graph would be a straight line thru the origin(or not... depends..)

thnx....
my teechu =P taught us jxt to label graph (in writing part) but in the mark scheme it quoted draw graph...

aah! u saved me thnx buddy =D

u'll gain a mark more if u include the graph trend like +ve or -ce gradient
inceasing gradient of decreasing gradint
but be sure before u write

 

[sksuriza]

n wt abt straight lines or curves??

 

[hallaballa]

just state as it is
u dont ned to draw a real graph
u just need to state how the graphs looks as straight or curves with nature of gradient if u are sure ONLY

yes u need to have an idea of a straight or curve line and +ve or -ve gradient
and label the axis

oh btw. when there is a CRO used... u also get a mark for drawing a graph that u might see on the screen. then calibrate (tell how u calibrate- like 1 box is 1cm..)
and ur welcome

oh and they wont give curves... havent done any curve till now. :T

curves can come in cases or LDR or thermister

 

[awesome94]

but u know... whenever theres an equation for curves, i use the logs and make it into y=mx+c form.. then i get a strt line..
its much less confusing

BEST OF LUCK FOR TOMOROW~!!!!!

I think that physics design is a very important course because it helps me to understand the laws of nature. The physics design class has helped me to understand how I can use science in my everyday life, whether it is by using science as an energy source or science as a way of communication. Visit https://masterbundles.com/graphics/icons/ for more details. I have also always been good at learning new things quickly, which is why I am able to keep up with my current job.
