- Homework Statement
- Experimentally determine the value of ‘g’ by measuring the displacement, velocity, time, and acceleration of an object (using LoggerPro) in an elevator.
- Relevant Equations
- g=(ma - Fn)/m
d=vi*t + 1/2at^2
I’m kind of stuck on this one. I don’t see how we can use the acceleration of an elevator to find anything about the value of g. We can of course get the acceleration of the elevator, but it feels like that would be independent of gravitational strength. I feel like we need the mass or the Normal Force, but those aren’t things we’re asked to measure. We are just measuring kinematical values in an elevator climbing or falling several stories. Help!
