Calculating Gradient of a Graph
Prepared by,Rekha Morhan (5 Bakawali)
Physics
Gradients of straight-line graphs
•The gradient of a line is a measure of how steep the line is.•The gradient of a line can be positive, negative or zero if, moving from left to right, we have
y
x
a horizontal line
Zero gradient
y
x
a downwards slope
Negative gradient
y
x
an upwards slope
Positive gradient
•If a line is vertical its gradient cannot by specified.
x2 – x1
y2 – y1
the gradient =y2 – y1
x2 – x1
Finding the gradienty
x0
Formula:Formula:
The gradient =change in y
change in x
(1,4)
(-4,-1) (1,-1)
Calculation:m=(-1-4) (-4-1) = -5 -5 = 1
Calculation:m=(-1-4) (-4-1) = -5 -5 = 1
What is gradient of this graph?
Formula:Formula:
The gradient =change in y
change in x

Find the gradient of this gradient.s
m = 7-2 10-0 = 1 2 = 0.5cms
m = 7-2 10-0 = 1 2 = 0.5cms
cm
Formula:Formula:
The gradient =change in y
change in x
