Vertical uptoss motion refers to the motion of an object with initial vertical upward speed, acceleration and constant g uniform acceleration, which can be divided into two processes: upward throwing uniform deceleration motion and falling free fall motion. It takes equal time to rise and fall in the synthesis process of Vo uniform straight line motion at initial speed and free falling motion.

Vertical uptoss speed Calculator tool：V_y=V_y0-gt

V_y = end speed

V_y0 = start speed

g = gravity acceleration

t = time
