    Experiment Limits
AI Thread Summary
Limits in an experiment refer to the constraints and assumptions that define the scope of the study. These can include factors such as time frames, environmental conditions, and specific variables like temperature and friction. The nature of the limits varies depending on the type of experiment being conducted. For instance, some experiments may assume negligible friction, while others might overlook heat exchange with the environment. Understanding these limits is crucial for interpreting the results accurately.

hello
if i did an experiment, and a question was asked:
'Within what limits have you shown that...'
what do the limits mean?
do they mean like within the time frame, or like temperature, friction...etc?

By 'limits' they probably meant the constraints, restrictions, assumptions, etc. about the experiment.
 
It completely depends on the experiment itself. Different experiments have different limits of course. In one case, you might say friction is negligible while in another you can assume that heat lost to the environment(or gained) is ignored.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
