horizontal plane with variable acceleration and variable velocity (I actually stopped and restarted the motion about 200 degrees around or there about before completing the circle). I had wanted to do a case with uncertian accelerations, but a constant accel case might be easier to calculate...

Cool! Thats kind of interesting to see. I had been thinking about local reference frame actually in trying to solve my real problem, but I actually don't have a fixed global reference frame that I "know" about, at least not yet, that's a part of what this is about. I suppose I could...

okay-that at least makes sense theoretically, thank you. getting it to work in real life-looks like I have a bit more work to do. Neither of the 2 methods quite makes the true rectangle out of the data yet (as shown below, first averaging, then FFT) but the values are in the right range...

Okay, that helps a little. Maybe you can help me with the underlying understanding of the FFT as that seems to be one of my issues. I can guarantee for this particular experiment that the start and end point are always the same (to a relatively high degree of accuracy). So-I'm trying to...

Hi, I'm having trouble with the application of filtering to real acceleration data. I have looked at a lot of recommendations, filtering through fft, butterworth high and low pass filters, and I'm not finding something that's working for my data and I'm looking for recommendations. I...

Homework Statement A car is driving straight southward, past a service station, at 100 km/h. The surface pressure decreaes toward the southeast at 1 Pa/km. What is the pressure tendency at the service station if the pressure measured by the car is decreasing at a rate of 50 Pa/3h? (Hint: draw...
