viteza corpului aruncat pe verticala de jos in sus Vo- g*t
perioada, T = Δt / N timpul in care punctul material face o rotatie
inaltimea max atinsa de corp aruncat pe verticala Vo^2 / 2*g
variaţia vitezei unghiulare într-un interval de timp Acceleraţia unghiulară, ε =
miscare circulara uniforma e miscarea pe o traiectorie circulară în care punctul material parcurge pe cerc arce egale în intervale de timp egale.
viteza unghiulara, ω = Δα/ Δt = 2*π/Δt se masoara in: rad/s
relatia dintre perioada si frecventa ν =T^(-1)
viteza liniara = ______________ dintre viteza unghiulara( ω ) si raza(R) produsul
viteza liniara = ______________ dintre distanta_parcursa(l = 2πR) si timp(Δt) in care a fost parcursa raportul
timpul de urcare a unui corp aruncat vertical in sus = ___________ dintre viteza_initiala (Vo) si acc.gravitationala (g) raportul
