Motion and Graphical Analysis | Lab #3 | Name: | | Class: | | Date: | | Purpose: | The purpose of this lab is to be able to analyze displacement, velocity, and acceleration quantities, determine the velocity of an object undergoing constant motion, and determine the speeding up of an object undergoing consistently accelerated straight-line motion. | Procedures: | Apparatus: | Microsoft Excel | Required Materials: | * Tape 1 & 2 from Lab 3 | | 1. Print both tapes in Lab 3 and use scotch tape to fasten 2 and 2b together to form one long tape. 2. Using excel design a spreadsheet to present data from both experiments and have the spreadsheets calculate the average velocity and the average acceleration for each time interval. 3. Produce displacement-time graphs and velocity-time graphs for each experiment. 4. Use the data provided in Lab 3 for the car on the highway that students lined a road standing 25 m apart and used stopwatches to record the time when a car traveling on a highway pass each person. 5. Create a Position vs. Time graph with slope shown on the graph. | Data: | Tape 1 Time (s) | Position (cm) | 0 | 0 | 0.10 | 0.06 | 0.20 | 0.24 | 0.30 | 0.54 | 0.40 | 0.96 | 0.50 | 1.50 | 0.60 | 2.16 | 0.70 | 2.94 | 0.80 | 3.84 | 0.90 | 4.86 | Tape 2 Time (s) | Position (cm) | 0 | 0 | 0.10 | 1.50 | 0.20 | 3.10 | 0.30 | 4.70 | 0.40 | 5.90 | 0.50 | 7.50 | 0.60 | 9.10 | 0.70 | 10.40 | 0.80 | 11.70 | 0.90 | 13.40 | Car on Highway Time (s) | Position (cm) | 0 | 0 | 1.3 | 25 | 2.7 | 50 | 3.6 | 75 | 5.1 | 100 | 5.9 | 125 | 7.0 | 150 | 8.6 | 175 | 10.3 | 200 | | Evaluation of Data: | Calculations: | Use this formula to determine average velocity (cm/s): (Xf-Xi)/(tf-ti). An example using Microsoft excel would be (B3-B2)/(A3-A2). | | Graphs: | Tape
