Gravitation
Gravitation is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. Earth's gravity is what keeps you on the ground and what makes things fall. Gravity is a fundamental force in the universe, and it plays an important role in space and astronautical engineering. Understanding the gravitational forces between celestial bodies is crucial for designing spacecraft trajectories, calculating fuel requirements, and predicting the behavior of satellites and other objects in orbit. Gravitational forces also affect the structure and behavior of stars, galaxies, and other astronomical objects.
