AI Thread Summary
The discussion focuses on investigating the relationship between elevator velocity and the mass inside it, proposing a method that includes measuring travel time for different masses. The participant suggests plotting velocity on the y-axis against the inverse of mass on the x-axis to analyze the data. There is uncertainty about whether to include uncertainty approximations in the results table, despite not conducting the experiment. The equations provided support the relationship being explored, specifically v = k/m. Overall, the thread seeks clarity on graphing methods and data presentation for the lab investigation.

Homework Statement


I am planning a lab where I am investigating the (inversely proportional) relationship between the velocity at which an elevator is moving and the mass inside an elevator.

Method:
1. Estimating distance the elevator is going to travel.
2. Have a mass of 100 kg inside the elevator (this is later increased)
3. Measuring the time it taken to go from the bottom to the top floor using a stopwatch
4. Recording the time.
5. Repeat for larger masses

1. I am wondering what would be an appropriate graph to plot using the data obtained.
2. Should I put uncertainty approximations in the table of results? (ever though I am not actually going to carry out the experiment)

Homework Equations


v = s/t
v = velocity (m/s)
s = displacement (m)
t = time (s)

v = k/m
Where v = velocity (m/s)
k = the "lift constant" (something I came up with) (m kg/s)
m = mass inside the elevator (kg)

The Attempt at a Solution


1. I think I should graph v on the y-axis and 1/m on the x-axis and then find the slope, but I'm not sure if that will be appropriate.

(dy/dx = dv/dm ?)

2. No?

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
