1. The problem statement, all variables and given/known data 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. Relevant 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?
