The force that keeps an object in orbit is called centripetal force. This is the force that pulls an object towards the center of its circular path.
Centripetal force is directly related to gravity, as it is the force that is responsible for keeping objects in orbit around larger bodies, such as planets or stars. Without gravity, there would be no centripetal force and objects would not stay in orbit.
The amount of force required to keep an object in orbit is affected by the mass of the object and the mass of the body it is orbiting, as well as the distance between them. The closer the object is to the body it is orbiting, the greater the force required to keep it in orbit.
Yes, an object in orbit can experience other forces such as atmospheric drag, solar wind, and gravitational influences from other celestial bodies. These forces can affect the orbit of the object and potentially cause it to deviate from its intended path.
The speed of an object does not affect the force needed to keep it in orbit, as long as it is traveling at a constant velocity. However, if the speed of the object changes, the force required to keep it in orbit will also change. For example, if the speed increases, the force needed to keep the object in orbit will also increase in order to maintain a stable orbit.
