Distance it takes for terminal velocity

AI Thread Summary
Calculating the distance for an object to reach terminal velocity in a viscous liquid is complex, as it does not involve constant acceleration. Stokes' law applies to the motion of spheres in a viscous medium, but the acceleration changes as the object accelerates until it reaches terminal velocity. The discussion suggests that while SUVAT equations are typically used for constant acceleration, they may not be applicable in this scenario. A resource on drag is provided for further understanding. Experiment design should consider these factors to accurately investigate Stokes' law.

Hi, i just wondered if it is possible by calculation to determine how far in a viscous liquid it would take for an object (sphere, ball bearing) to reach terminal velocity. I have to design an experiment to investigate Stokes law. Could i use suvat equations as it is constant acceleration?

Thanks

Unfortunately it is not constant acceleration.

Here is an interesting lecture on drag that you might benefit from:

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
