SUMMARY
The trajectory of a rocket launched straight up is parabolic due to the influence of gravitational forces acting on it after engine cutoff. While rockets initially ascend vertically, they transition to a ballistic trajectory, which can be described as a segment of an ellipse, with the Earth’s center as one focus. The velocity of the rocket at launch plays a crucial role; if the velocity is less than the escape velocity, the rocket will follow this parabolic path. Understanding these dynamics is essential for analyzing rocket landings and trajectories.
