# Investigating elevator in motion

#### Mathbather

1. 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)

2. 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)

3. 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?
