Lab Activity #2: Constructing a graph. Earth's gravitational acceleration; The following data represents the speed of a steel ball falling from the Freedom Tower measured at different time instants. Time ( s ) 3 5 Speed (m/s) 8 34 52 66 86 Your task is to plot the data in Figure # 6 using the x-axis for time and the y-axis for speed. 1. Write a suitable title. 2. Write the name of the axes and their units in parenthesis. 2 3. Design the scale for each axis. SHOW YOUR WORK. Time axis scale design: Data range: 9-1 =8s_ _ Divisions available: 100 divisions V = - 8 s 100 div = 0.08 s/ div Scale:_0.10 s/ div Speed axis scale design: Data range:_86 m/s - 8 m/s =78 m/s_Divisions available:_100 div_ V = (78 m/ s)/ (100 div) = 0.78 (m/ s)/ div Scale: 1.0 (m/s) / div 4. Indicate the time and speed axes scales in the graph. 5. Indicate the axes values in both axes. 6. Plot the data points. 7. Draw a trendline. 8. Calculate the slope of the trendline. Indicate below the coordinates of the points that you will use to calculate the slope. The slope is calculated by MS Excel or by hand as below. Point 1 coordinates: ( time 1, speed 1 ) = (_1.0 s_ _11.6 m/ s_) Point 2 coordinates: ( time 2, speed 2) = (_9.0 s_ 86.8 m/s_) Show below your slope calculation: slope = 56:8 m/s- 11.0m/$ = 9.4 m/$2 9.0 s - 1.0 s The slope is the gravitational acceleration close to the surface of Earth calculated from this experiment.
