vertical speed calculator enter the value and click "calculate", the calculation result will be displayed. vy = v0 - gt v0 = vf + gt g = ( v0 - vf ) / t t = ( v0 - vf ) / g choose a calculator: --choose-- initial vertical velocity acceleration due to gravity time vertical speed time initial vertical velocity (v0): m/s acceleration due to gravity (g): m/s2 acceleration due to gravity (t): s vertical speed time (vy): m/s calculation result:
