Parabolic trajectory equation 2024年11月09日01点已下架

Parabolic trajectory equation When an object is launched near the surface of the Earth and resistance is ignored, its trajectory follows a parabolic shape. If the initial height of an object is h 0, the initial velocity is v 0, and the trajectory angle is 0, then the parametric equation of the parabola is y (t)=h 0+(sin 0) v 0 t - (g/2) t 2 x (t) = (cos 0) v 0 t Free fall calculation If the height is known, this free fall calculator can determine the speed and fall time of an object falling vertically to Earth or other planets. Not considering air friction. If the speed is known, the calculator can also calculate the fall height and time; If the time is known, the calculator can also calculate the impact velocity and altitude.
