Unformatted text preview: Physics 195 – Straight-line Kinematics 13 HOW TO DRAW A GRAPH 1. Obtain graph paper; 5 or 10 squares to the inch, or 10mm to the cm. 2. Sharpen pencil. Do not use ink or ballpoint. 3. Choose a scale for your variables that utilizes most of the paper in both dimensions. The scale should correspond to the main divisions of the graph paper (1,2,3…2,4,6…5,10,15…avoid choices like 3 m/s = 2 cm). 4. Draw the x and y axes. 5. Indicate the scale divisions to the left of the y axis and below the x axis, respectively. 6. Label each axis with the name of the variable and its units. Do not abbreviate the name of the variable. 7. Draw your data points by marking the position with a sharp point, surrounded by a small circle. 8. Draw a smooth curve that fits through your data points without necessarily passing through each data point. Some points will lie above the curve, some below. If the data indicate a straight line, use a ruler. Do not force the line through the origin even if you think it should straight line, use a ruler....
