Graphing

The intention of this topic is to learn more about graphs in laboratories. When conducting experiments, one can present data in various ways. One of these is through graphs. Normally, tests compare at least two components. For example, how a process changes over time. If that process involves distance, a grid of distance against time can be plotted. The distance can be calculated using any proper measurement such as centimeters. If the distance cannot be represented on a graph paper, the data is drawn to scale. This topic, therefore, looks at different types and parts of a graph.

General Overview of Procedure

In this lab, we learn about drawing of graphs. All graphs have y- and x- axes. From the experiments’ results, the data is presented in the form of a diagram. The axes signify variables that are supposed to be represented, for example, time against distance. Similarly, points are mapped depending on the results obtained from the experiment. For example, if it takes 10 seconds for an object to move 20 centimeters, we map ten on the x-axis to 20 on the Y-axis, and the point of intersection between the two is where we put the coordinate.

After all the coordinates are plotted, the graph is then plotted. It can either be a line or a curve. The decision is determined by the alignment of the marks.

Results

For activity 2, the graph is a smooth curve. It cannot be drawn into a straight since most of the points are not in-line. For a graph to be drawn into a straight line, most of the coordinate points should be lined up.

For activity 3, the first question, the change in x is:

5.9-0=5.9

The change in y is

8-1=7

The slope of the line is

Slope = change in y / change in x

5.9/7 = 0.84285714

For activity 3, part (ii) the graph obtained from the given data is a curve. Calculating the slopes of the specific points of the grid gives the following results:

x

slope

2.0

1

3.0

1.3

4.0

3.3

5.0

3.6

The graph of x against slope is not a straight line.

For activity 4 question (I) the points of the experimental grid do not lie right on top of the points of the theoretical graph.

Drawing a straight line from point to point would not give an identical graph to the curve. The reason for this outcome is the irregular changes that take place. The gradient of the curve changes at any given point, while the incline of the straight line...
