## Resource summary

 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 Practice : https://isaacphysics.org/questions/ch_a_p6?board=gcse_alevel_transition_skills
