Experiment 2: Acceleration
Student A, Student B, Student C
PHYS 130 – XX
(Date goes here)
Below is a template for your physics lab report. When writing this lab report, pretend that your target audience is a student who is also taking physics, but has not done the experiment yet.
Introduction
In this section, you should write a short paragraph about the purpose of this experiment. Things that you could include are:
What physical quantities are you trying to measure?
What hypothesis are you trying to test?
You can briefly mention the final conclusion here, but save the reasoning behind how you get to your conclusion until the Conclusion section at the end of the report.
Things that you don’t need to include are:
You do not need to include historical background.
You don’t need to discuss the educational value of this experiment.
Method
In this section, you write a paragraph (or two) to briefly explain the equipment used and outline how the experiment was done.
Explain the purpose of the equipment and how they work.
If it is a sensor, you can also specify what quantities it is measuring (Is it measuring position? Velocity? Time?)
Explain the experiment setup.
Outline what was measured/recorded. Also include how many data points.
Do NOT copy the procedure from the lab manual.
Data
Every item in the “Data analysis and write-up” section in your lab manual has to be somewhere in this lab report. Some item can go under the Data section, some can go under the Results section, and some can go under the Discussion section. I’ll leave it up to your to decide what goes where.
Present your data here. Usually you will repeat a measurement multiple times, so a table with the data that you have recorded is often a good way to go. See example below.
Table 1. Explain what this table is.
Specify what physics equation was used to calculate what quantity.
You can include average and standard deviation in this section.
If graphs are required for a specific experiment, include them here.
Results
The final results goes here. Using experiment 2 as an example:
Calculate the percent difference between the two acceleration values (without weight and with weight)
Calculate the for without weight and with weight.
Compare to by calculating the percent error. Again, one for without weight, one for with weight.
Discussion
Comment on the quality of your measurement based on the standard deviation of your data.
Comment on the accuracy of your measurement based on the percent error found in the previous section. Discuss the possible sources that might have caused this difference.
Conclusion
Based on your results above, what do you conclude? Make sure to include the reasoning on how you arrived at your conclusion.
