SUMMARY

This discussion focuses on investigating the relationship between elevator velocity and the mass inside the elevator, specifically using the equation v = k/m, where v represents velocity in m/s, k is a lift constant, and m is mass in kg. The proposed method includes measuring the time taken for an elevator to travel a set distance with varying masses, starting with 100 kg. The participant suggests plotting velocity on the y-axis against the inverse of mass (1/m) on the x-axis to analyze the data, and questions the inclusion of uncertainty approximations in their results table.

PREREQUISITES
  • Understanding of basic physics concepts, particularly motion and forces.
  • Familiarity with graphing techniques and data analysis.
  • Knowledge of the equation v = s/t for calculating velocity.
  • Basic understanding of uncertainty in experimental results.
NEXT STEPS
  • Research how to effectively plot inverse relationships in graphs.
  • Learn about uncertainty propagation in experimental data.
  • Explore the concept of lift constants in physics and their applications.
  • Investigate methods for analyzing experimental data using statistical tools.
USEFUL FOR

Students conducting physics experiments, educators teaching motion concepts, and anyone interested in the dynamics of elevators and forces in motion.

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?
