Question

1. Organize: On the grid below, plot the car's progress for each of the three trials. The distances are labeled from 1 to 3 m on the vertical axis. Label the tick marks on the horizontal axis in equal intervals, depending on the times you measured.

A. Use a different color for each trial. Record the color you chose for each trial in the table.
B. For trial A, plot a point on the graph that corresponds to the time recorded at each of the four distances: 0 m, 1 m, 2 m, and 3 m. Use a straightedge to draw a line from the point (0, 0) to the point at 0 m, then from this point to the third point, and then from the third point to the fourth point. C. Repeat for the other two trials.

Answer 1

The question involves creating a graph to depict a car's motion over time, with distance as the y-axis and time as the x-axis, labeling axes, using different colors for each trial, and finding the average velocity by calculating the gradient of the plotted lines.

Step-by-step explanation:

The student's question is about plotting a car's progress on a graph to analyze its motion over time. This task involves creating a Distance vs. Time graph, which is a visual representation of the car's motion during each of three distinct trials. To organize the information, one would:

1. Measure the time it takes for the car to travel set distances during each trial.
2. Calculate the average time for each distance using the recorded times.
3. Plot these averages on the graph paper, with the distance on the y-axis and time on the x-axis.
4. Label the axes with the respective variables and units, such as Time (min) for the x-axis and Distance (m) for the y-axis.
5. Choose a scale that fits all the data points efficiently.
6. Draw straight lines connecting the data points for each trial in different colors, and record the color used for each trial in a table.
7. Finally, determine the gradient of the line, which represents the car's average velocity.

Additional steps include determining the frequency of a ticker timer if used, setting up an experimental track, and conducting speed measurements after a collision.
