Uniformly accelerated linear motion conclusion

I'm working on a physics report and need a sample draft to help me learn.

In this lab report, my part is objective and discussion/ conclusion.

For objective part, my professor left some guideline:

What is the physics concepts/theory/law to be investigated in this experiment? It is one or two sentences in your own words.

For discussion/ conclusion part, my professor left pretty specific instruction:

This is the most important part of the lab report. It is where you describe whether your results support the physics principal being investigated in the lab. Begin the discussion with the purpose of the experiment. Briefly explain the theory concept that was tested. Then state only the key results (with uncertainty and units) quantitatively with numerical values; do not provide intermediate quantities. Discuss the relationship between your raw measurements and your final results; the relationship between quantities in the graph; relationship between the independent and dependent variables. All questions from the lab manual should be answered in the narrative form.

How can you tell that the cart was not moving with constant velocity based on the position vs time graph generated in this experiments? What attribute of velocity vs. time graph tells us the magnitude of acceleration? What attribute of position vs. time graph related to the magnitude and direction of acceleration and how? Support all of your answers with your data.

In run 1, how do the values of acceleration you calculated using position vs time graph and velocity vs time graph agree with each other? Compare graphs generated in Run 1. In run 2 how different is the shape of position vs. time graph in comparison to run 1? In run 3 why is the acceleration negative while the velocities are positive? How did the car move in this case? In run 4 the acceleration is positive even though the cart is slowing down with time. Why? Why are the velocities negative? If you had known the acceleration would you be able to deduce whether the object was speeding up or slowing down? Explain your reasoning using the results of the 4 runs you have performed in this lab. On average, how close does the value of acceleration from the position vs. time fit agree with the value of acceleration from velocity vs time graph?
