Sir I have my paper 33 tommorow.I wanted to ask you is it necessary to write the uncertainty in the instrument along with readings in q1?.And do we right readings with stopwatch to 2 d.p because uncertainty is +- 0.01s ?.Pls if you can answer will be greatly appreicated.

ti got an exam tomorrow like u as well,but time is measured to 1d.p and if in a calculation so s.f. is ur concern

Y intercept also has a unit ri8? Then -0.919 m?

When plotting error bars, do you plot the absolute uncertainty or the percentage uncertainty? If you could make a video on plotting error bars etc. that would be most helpful. Thanks

Should you be taking your lowest Y value as outside of your data set? Your triangle for the gradient extends beyond the points you've plotted which I've been taught as something to avoid doing, as I will lose a mark for my graph.

+Alex Lawrence Generally once the line of best fit has been drawn on, which usually stretches beyond the data points, values like the gradient are found using points on the line, rather than the data points, and at least for my exam board, you lose marks for using data points if the line is clearly visible, with the exception of (0,0) Sorry for a block of text on a month old comment; hope it helps either way. :)

No I'm well aware of this

It's that my teachers have taught me not to take points on the line that extend beyond my data set's boundaries
