Question
Hello, I have a lab tomorrow, and I am very bad at physics. I want to prepare myself for the lab since it's hard and long. Pictures 1&2 are explanation of the lab, page 3 & 4 are the lab that we're assigned to do. Just explain to me what I should do in each part.
There will be a lot of measurments and stuff like that. But I want you to put random numbers in each column (assuming you have equiment in front of you) and then explain how you answered that (if there was a formula or something).
Answer questions 1 - 4 briefly. <=== THIS IS THE MOST IMPORTANT THING!! (Please answer them correctly)
This is really hard for me. I really need your help. I just want to get the idea of the lab.
you might need to open the pictures in a new tab. so you can view it clearly
These are the links for the pictures:

Explanation / Answer
Force versus Acceleration (no weights on cart)
Force versus Acceleration (300 g weight on cart)
Q-1
from F=ma
since force is proportional to acceleration the graph is always a straight line irrespective of mass.
You can observe this from the two graphs.
Q-2
slope of the line is change in force to the change in acceleration.
Q-3
percent discrepancy = 300-210 = 90%
Q-4
mass to force
