Question is very simple that if orbital motion obeys ideal law's then there must be a ideal force that runs this systen...Can you identifid the force?...waiting your ideas
Huh? Do you really not know what "force" controls orbital motion?Kaka said:Question is very simple that if orbital motion obeys ideal law's then there must be a ideal force that runs this systen...Can you identifid the force?...waiting your ideas
Small additional forces cause small changes in the orbit, for major changes, you need large influences. So for example to cause the Earth to leave the Solar system, you would have to apply enough force for a long enough time to increase its orbital velocity by some 12 km/sec. To cause it to fall into the Sun, you would have to decrease its velocity by nearly 27 km/sec. Since the forces presently acting on the Earth are small and many times acting counter to each other, there is not much chance of them causing any major disruptions to the Earth's orbit over the foreseeable future.hilbert2 said:A more relevant question is whether the orbits are stable, i.e. can't be completely messed up by small additional forces (forces between planets, relativistic effects...).
The lack of disturbance in orbital paths is due to the balance between the gravitational force of the central object and the inertia of the orbiting object. The gravitational force pulls the object towards the central object while the inertia of the object causes it to continue moving in a straight line. These two forces create a stable orbit.
The planets and other objects in our solar system stay in their orbits due to the conservation of angular momentum. This means that the speed and distance of the orbiting object remain constant unless acted upon by an external force. In the case of our solar system, the force of gravity from the sun is the primary factor keeping the planets in their orbits.
Yes, orbital paths can change over time due to various factors such as the influence of other objects, changes in the mass or velocity of the orbiting object, or external forces such as collisions. However, these changes are usually gradual and do not significantly affect the overall stability of the orbital path.
Scientists use mathematical equations, such as Newton's laws of motion and the law of universal gravitation, to calculate and predict orbital paths. These equations take into account factors such as the mass, distance, and velocity of the objects involved to determine the shape and stability of the orbit.
While most objects in our solar system maintain stable orbital paths, there are some exceptions. For example, comets and other small objects can experience changes in their paths due to the gravitational influence of larger objects or other factors. Additionally, in very rare cases, objects may be ejected from their orbits entirely due to strong gravitational forces or collisions.
