General special relativity question

AI Thread Summary
Special relativity can indeed address situations involving acceleration, contrary to the common belief that it only applies to non-accelerating scenarios. The key distinction between special and general relativity is that special relativity is applicable in the absence of gravity, which affects the curvature of space-time. While special relativity can accommodate acceleration, it requires at least one inertial reference frame to maintain consistency. This allows for the analysis of accelerating particles without invoking gravitational effects. Understanding these nuances clarifies the relationship between special and general relativity.

I'm reading in my textbook (and have a homework problem on) special relativity dealing with an accelerating particle. I thought special relativity dealt with non accelerating situations only though? Isn't that the distinction between special relativity and general relativity? I'm clearly missing something here lol :smile:

Special relativity deals with situations where gravitation isn't present. There's nothing wrong with acceleration due to forces other than gravity.

The idea that special relativity doesn't deal with acceleration is a popular myth. And that myth is false. Special relativity can handle acceleration and can handle it quite well.

As D H says though, special relativity only applies when gravity is not present. That's because gravity curves space-time. Special relativity only works when there is the possibility of flat* space-time called Minkowski space-time.

*Even in special relativity, space-time can be curved in an accelerating reference frame. For that reason, special relativity typically has the following requirement to stay consistent: at least one reference frame must be an inertial frame (and that frame is typically used to keep track of the [inertial] velocities of things). As long as that is met, other frames can accelerate around all they like.

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}...
