How to prove the gradient is = to something easy and safe way
Write the equation of the line
Compare to y = mx +c guaranteed mark
What’s the reason error bar not shown on graph?
What must be said
Because the ABSOLUTE UNCERTAINTY (which is what’s plotted here) is too small compared to measurements
So that on the graph scale it’s too small to be seen !
Why would measuring something using a protractor or otherwise be a LESS PRECISE way of finding angle than CALCULATING USING GRADIENT
precision is defined as how close Independent measurements would be
And so for a protractor INDEPENDENT MEASURMENTS WOULDNT AGREE AS MUCH, THEREFORE LESS PRECISE !
How ti answer calculation x 6 marker, what ti say for extra explanation
Extra wacky content? Example with life in esrth
Always try explain the answer first WITHOUT CALCULATING
- then calculate to prove
This way you’ll get all the marks
2) also try include wacky stuff, ti make it sound through ful
- such as temp not the inky fsctor involved , so even if temp ranges a bit there still could be life
- life is suited for some beings, others can survive ar diff temps, so doesn’t necesduktl mean temps outside range might not be suitable…
Again precision defintion
What’s always the best way of finding , measuring or calculating over a gradient ?
Precision is defined as how much indepenent measurments agree with each other
Cslcuskting always gives a value which agreed with the indepenent measurements
Measuring DOESNT
