1
Q
How should we draw a triangle in the graph to get the gradient
A
Make a big triangle from the line.
2
Q
How to calculate percentage uncertainty in the gradient
A
(best fit gradient - worst fit gradient / best fit gradient) x 100
3
Q
How to draw error bar
A
Eg. if uncertainty +- 0.1
You do 0.1 above the point and 0.1 below the point
4
Q
What is length of error bar
A
2x absolute uncertainty
5
Q
How to calculate absoulte unceratinty of gradient of line
A
best fit - worst fit gradient
