I was watching The Feymann online lectures and he talked about the arrow of time.And entropy etc.
I have some questions.
1-Can ve say non-conservative force are time irreversible, but conservative force are time reversible ?
2-So From one , If a non-conservatice force acts on a system that system will lose energy and that energy has something with entrophy.(I think that way ).And It must be defined by some equation
##ΔS=∫\frac {Q} {T}##
here Q is energy lost or another way, ##Δ(ME)=ΔW_{non-conservative force}=Q##
T is the tempeture of the system (I thought this relationship myself so it could be wrong or right )
Here Q be aslo something else like If two atoms colllide some energy will lost.That energy also can be Q.
3-In closed systems ΔS=0 would be zero ?
4-If closed system ΔS=0 then how could we say entropy always increases (I know its not "always" its "almost" always, but in here is İn a closed system.Entrophy will be same for a long time.So entropy didnt decreased so.. ?
5- Seems that there's a strict relationship between time and entrophy.Can we say with time some information lost ? (Or hidden information )
