Orbital Mechanics is the study of the motion of objects in space under the influence of gravitational forces. It helps us understand how celestial bodies like Earth, Moon, and Satellites move in their orbits, allowing for accurate predictions of their positions over time. This field combines physics and mathematics to analyze trajectories, velocities, and the effects of various forces. By applying principles of Newton's Laws and Kepler's Laws, scientists and engineers can design spacecraft missions, ensuring they reach their destinations efficiently and safely.
