AI Thread Summary
Errors in a ballistic pendulum lab can stem from various sources of variability, including inaccuracies in measuring pendulum heights, masses, and impact distances. Friction is a factor in physical systems but is often negligible in this context. The reproducibility of the spring mechanism's release also plays a crucial role in ensuring consistent results. It's essential to consider all potential sources of error to understand their impact on the experiment's outcomes. Thoroughly evaluating these factors will help improve the accuracy of the lab results.

What can cause errors in ballistic pendulum lab?
Does friction counts in some of these causes?
 
Physics news on Phys.org
Friction is always a factor in physical systems, but is probably negligible. Can you provide details of your problem? No one here can know what your "pendulum lab" is.
 
Please don't assume "usual". I work in industry and don't know your assignment, course, instructor, book, or even if you're in high school or college.

You should think about all sources of variability and error. How accurately do you measure pendulum heights? Masses? Distance to floor impact? Does your spring mechanism release reproducibly every time? You can probably think of more. All of them contribute to variance in the answer.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

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}...
