Laws Newton's laws

AI Thread Summary

Numerous participants emphasize the applicability of Newton's laws in everyday situations, suggesting that real-world examples are abundant. They encourage looking at common scenarios to identify which of Newton's laws apply, such as objects in motion, forces acting on bodies, and interactions between objects. The discussion highlights the importance of understanding these laws through practical observation rather than seeking complex examples. Participants also suggest that AP Physics-B students can find relevant situations in their daily lives. Overall, the conversation underscores the idea that Newton's laws are foundational and can be recognized in a variety of contexts.

does anybody know where I can find a LOT of situations where I have to identify which law of Newton it fits to?

If not, can somebody give me situations in which I have to indentify?
This is AP physics-B level so something not that convoluted

Thanks

What are you talking about? Just look around around you. You can apply it to practically EVERYTHING!

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...
