Errors: Random, Systematic, and Human

AI Thread Summary
The discussion focuses on understanding different types of errors relevant to a lab report on momentum and energy conservation in collisions. Random errors are unpredictable fluctuations that can affect measurements, while systematic errors are consistent inaccuracies that arise from faulty equipment or experimental design. Human errors refer to mistakes made by the experimenter during data collection or analysis. The original poster seeks guidance on how to articulate these errors at a university level, emphasizing the need for a more in-depth approach than what their teacher provided. The conversation highlights the importance of distinguishing between human and non-human errors, as well as the nuances of systematic and random errors.

Homework Statement


Hello! In our class, we just completed a lab on momentum and energy conservation in collisions. It was a computer simulation. Although, for the lab report, the teacher wants us to write the random, systematic, and human errors. Can someone describe what each error means? What is a human error? What is a systematic error? What is a random error?

Have you asked your teacher ?(By the way: I see that you haven't responded to the replies people made to your other thread. )
 
I actually have asked my teacher but his descriptions were not very clear. Typically, i have relied on some online resources about how to write errors, but this teacher expects a more in-depth approach - a university-level approach. So I was hoping for some advice/ instruction on how the people on this form approach this section of a lab report. A lot of you are university-level students/grads/PhDs so maybe I can get some input on how a university level Error's part of a lab report should look, and what it should include.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
