Graph Skills

Question	Answer
Which graph scales are not usually accepted?	3's , 6's , 7's
All points must be accurate to how many squares?	1/2 a square
What size on the page must the plotted points take up?	Over 1/2
How do we work out the gradient?	change in y / change in x
What is the equation for a line?	y=mx+c
Which letter represents the y intercept?	C
The quantity which is stated first always goes on which axis?	Y axis
What must we remember to do to y=mx+c (and other values mathematically worked out) in physcis?	Change the letters / units (e.g. y=1/2x to Weight=1/2(change in Length)
Tangents are used to ....	Find the gradient of a curve
Tangents should be drawn....	Parallel to the graph line at the point
R = pL/A + k (y axis = R, x-axis = L) What is gradient and intercept?	Gradient = p/A (as multiplied by x-axis) Intercept = K (as alone)
L/T = λf + D (y axis = T^-1 , x-axis = λ) What is gradient and intercept?	Gradient = f/L (as y axis = 1/T so we divide across by L, and we mutlily f/L by the x-axis) Intercept = D/L (as alone divided by L)
s = 1/2 gt^2 would have an intercept value of....	0
