Question

vreau sa imi  spuneti si mie doar formulele si cu ce se masoar a ele in sistem international la fizica formulele pt clasa a 6a

Answer 1

voi spune formulele pentru ce se face pana acum la clasa a VI-a

[tex] \ \textless \ l\ \textgreater \ _{SI}=m (metru) [/tex]

$\ \textless \ t\ \textgreater \ _{SI}=s (secunda)$

v=(lf-li)/(tf-ti)=Δl/Δt

$\ \textless \ v\ \textgreater \ _{SI}=[tex] \ \textless \ l\ \textgreater \ _{SI}/[tex] \ \textless \ t\ \textgreater \ _{SI}=m/s (metru pe secunda)<span>$

$\ \textless \ m\ \textgreater \ _{SI}=Kg (kilogram)<span>$

$\ \textless \ V\ \textgreater \ _{SI}=[tex] m^{3}$ (metru cub) [/tex]

ρ=m/V

$\ \textless \ ρ\ \textgreater \ _{SI}=[tex] \ \textless \ m\ \textgreater \ _{SI}/[tex] \ \textless \ V\ \textgreater \ _{SI}=Kg/[tex] m^{3}$ (kilogram pe metru cub) [/tex]

$\ \textless \ F\ \textgreater \ _{SI}=N (Newton)<span>$

K=F/Δl

$\ \textless \ K\ \textgreater \ _{SI}=[tex] \ \textless \ F\ \textgreater \ _{SI}/[tex] \ \textless \ l\ \textgreater \ _{SI}=N/m (Newton pe metru)$
