A satellite is an object that orbits around another object in space. It can be natural, such as a moon, or artificial, created and launched by humans.
A satellite stays in orbit due to the gravitational force between it and the object it is orbiting. The satellite's orbit must also match the speed and direction of the object it is orbiting to maintain a stable orbit.
Gravitational force is the force of attraction between two objects with mass. In the case of satellites, it keeps them in orbit around a larger object, such as a planet or star. It also affects the speed and trajectory of the satellite's orbit.
Yes, satellites can also be affected by other forces such as air resistance, solar wind, and magnetic fields. These forces can cause satellites to change their orbit or even fall out of orbit.
Scientists use satellites equipped with specialized instruments to study the effects of gravitational force on objects in space. They can measure the strength of gravitational force and how it changes in different locations in space, providing valuable insights into the behavior of the universe.
