Question
what force causes a object to say in orbit
Answers
GPT-4o mini
An object stays in orbit primarily due to the balance between two forces: gravitational force and centripetal force.
1. **Gravitational Force**: This is the attractive force between the orbiting object (like a satellite or a planet) and the body it is orbiting (such as a planet or a star). The strength of this force depends on the masses of the two objects and the distance between their centers, as described by Newton's law of universal gravitation.
2. **Centripetal Force**: For an object to maintain a circular or elliptical orbit, it must constantly change direction. This change in direction requires a force directed towards the center of the orbit. In the case of planetary or satellite motion, this centripetal force is provided by the gravitational pull from the larger body.
When these forces are well-balanced, the object remains in a stable orbit. If the gravitational force was stronger than the required centripetal force, the object would spiral inward; if it was weaker, the object would drift away into space.
