Gravity

Gravity is a fundamental force of nature that attracts all objects with mass or energy towards each other. In the context of space and astronautical engineering, gravity plays a crucial role in determining the motion and behavior of objects in space. The gravitational force between two objects decreases as the distance between them increases, and this is the reason why objects in orbit around the Earth experience a continuous freefall towards the Earth, but never actually hit the surface. Understanding the effects of gravity is essential for designing spacecraft trajectories, calculating fuel requirements, and predicting the behavior of satellites and other objects in space. Additionally, the study of gravity has led to the development of technologies such as gravity sensors and gravity gradient stabilization systems, which are used in spacecraft to maintain their orientation and stability.
