1) Because of the inherently inaccurate nature of physics spa, and the need for plotting of a straight line to check for anomalous errors, most of the time, when doing Physics Spa Skill B, it is always wiser to fake the results rather than actually doing it..
i) First plot the tabulate for the 6 values ii) Measure experimentally only the first and last values iii) Proceed to draw a line (of course you must know it is a line!) using the first and last plots iv) Then work backwards to find the measurements for the other 4 values v) Because for skill B the teachers will only check for the raw values, so for the calculated values columns, you can anyhow write whatever values (they won't check) to suit the best fit line...
yes, use this method![/b]

Yar actually its not bad a method. Just that I'm not really used to work stuff backwards...

ya the trick here is...
sometimes when u are plotting log straight lines, it can be difficult to calculate backwards cos u'll have to you e^. so it is easier to fake any results(serious, any number!) toi suit your best fit line since i've checked out with my teacher that they will only check our raw data and it's impossible for them to check the calculated data (the one u used to plot in the graphs!)
