Question:
In my physics lab we used an ait track system, glider withflag, and 2 photogates to track the average velocity of the glider.We initially set the photogates 140 cm apart, and after eachrun, we moved the photogates 5cm towards each other until they wereonly 10cm apart. Here is a data table for this experiment:
Time in secound | Run Number |
2.99 | 1 |
2.73 | 2 |
2.47 | 3 |
2.23 | 4 |
2 | 5 |
1.78 | 6 |
1.57 | 7 |
1.36 | 8 |
1.16 | 9 |
0.97 | 10 |
0.77 | 11 |
0.56 | 13 |
0.38 | 14 |
0.19 | 15 |
Based on this information can you please help me find thefollowing:
1. Complete the data table you created by calculating theaverage velocity of the glider for each measurement in Part 2. Show1 sample calculation of average velocity in your report.
2. Create a graph by plotting average velocity versus thetime-between-gates data. The average velocity is plotted along they-axis, and time along the x-axis.
3. Add a 2nd order polynomial (quadratic) fit to your data onthe graph. Include the equation on the graph.
4. From the graph, determine the instantaneous velocity of theglider at the center of the air track. How does this compare toyour measured instantaneous velocity value in part 3?
