AI Thread Summary
The discussion centers on the four fundamental forces in the universe: gravitational, electromagnetic, strong nuclear, and weak nuclear forces. Participants clarify that Newton's second law (F=ma) describes the relationship between force and acceleration rather than being a fundamental force itself. References to external resources are provided for further information on these forces. The conversation emphasizes the importance of understanding these four forces in the context of physics. Overall, the thread aims to clarify misconceptions about the nature of forces in the universe.

In our universe, how many forces are there ?
I know Newton force ma=F and whozum just reminded me of electromagnetic force F~r, so where are the other two ?

strong and weak nuclear forces, gravity, and electromagnetic
 
F=ma is not a type of force, its a relationship between force and acceleration. The four are those that seiferseph just mentioned.
 

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}...
