GRAPH DRAWING
INTRODUCTION
Most
of practical in physics involves drawing of graphs as a key element in any
physics practical
RULES
USED IN GRAPH DRAWING
The
following are the most important rules required to follow in drawing a graphs.
i.
Write
the heading of your graph on the top of the graph by using capital letter
ii.
Underline
your heading
Eg.
THE GRAPH OF L (Cm) VS T2 (S2)
iii.
Select
the suitable scale and write it below heading to the right hand side.
Eg. SCALE
Vertical 1cm: 2cm
Horizontal 1cm: 0.1s
Note
To
present scale always used two ways either in words or ratio not otherwise.
iv.
Draw
the horizontal and vertical plane according to the instruction given.
All
the line intersed at origin 0.
For
example, draw the graph of L (cm) against T2 (S2)
THE GRAPH OF L
(cm) Vs T2 (S2)
SCALE
Vertical scale 1cm: 2cm
Horizontal 1cm: 0.1s
v.
Locate
the coordinate (points) to present the nature of the graph, draw the joining
each point on the planes
Eg.
vi.
Determine
the slope of the graph selecting any two points on the graph,
(i.e. A and B)
Slope
(M) = change in L (cm)/ change in T2(S2)
Note
Remember
to write the SI Units of your slope (M) if possible.
I.e.
(Cm/s2)
Determine
the x and y intercepts if that is required, from the nature of the graph.
Note
Most
practical questions depend on the graph:
