Suppose that the earth orbits the sun in a perfectly circular orbit. Does the sun's gravity force do any work

Question

(contiuned from question) on the earth as its orbits? Why or Why not?

Answer 1

Nope. The sun is in a sense what astronermers call a 'lomas nomar' which is latin for little movement.

The sun acts in essence as a requim. It simply encases the solar ashpyinction and creates a what is called a tidal flow mass. It is a space term for sonic wave. So the earth in essence accepts the lions share of the sholan movements.

Answer 2

The sun's gravity will always do work to hold the earth in orbit. Think of Newton's laws of motion, specifically; and object in motion stays in motion until it is acted on by a force. Since the earth is not traveling in a straight line, a force must be exerted to keep it moving in a circular manner. Kind of like tying a rope to a rocket, the rocket would go straight, but the string makes it circle a central point.

Answer 3

In that scenario, the sun would still be keeping the Earth in orbit due to its gravity, otherwise the Earth would just shoot off into space.

For the record not, the Earth's orbit isn't perfectly circular, but you quite possibly know that.

Answer 4

No it does not.

The gravity force is always perpendicular to the motion of the earth. And so the vector product is always 0.

Answer 5

................ EARTH'S GRAVITY is function of its rotation on its own axis ........... get a gyro and you will see .......... and the oval orbit around the sun is the function of a fine balanced orbits of all the planets in our solar system ........... of-course the sun has all the planets attracted towards it to balance the system ...... it is the focal point ........... but things cannot change without a catastrophic effect for all the planets ............. like another big bang if they all collide .......

Answer 6

yes its actually catapolting the earth around it.i dont think we have a perfectly circle orbit. i m not sure though. good question

Answer 7

yes
