Does gravitational force maintain the shape of the solar system? What is the mass of the Sun? Does Earth have a gravitational force which affects other stars? What are the effects of distance and mass on the gravitational pull of the planets?
Answer to: What would the Sun's gravitational force on the Earth be if the Earth had twice its present mass? Would the Earth's acceleration change?...
Jupiter, Earth, and Sun After Newton's triumph in explaining Kepler's laws, the next natural question was how the mutual gravitational forces between the planets affected their motion. Vast efforts were spent understanding how the exact solution to the two-body problem was possible: the key role...
To calculate the gravitational force between the Sun and the Earth, we can use Newton's law of universal gravitation, which states: F=Gm1m2r2 Where:- F is the gravitational force,- G is the gravitational constant, approximately 6.674×10−11N m2/kg2,- m1 is the mass of the first obje...
Assertion : A force act upon the earth revolving in a circular orbit about the sun. Hence work should be done on the earth. Reason : The necessary centripetal force for circular motion of earth comes from the gravitational force between earth and sun. ...
The first part defines gravitational forces as a force that creates an oscillation when the moon is reaching the Perigee, the smallest distance between the Moon and Earth during its rotational movement around Earth. It has a small amplitude and large period. Unlikely other authors, we do not ...

The gravitational force exerted by the Sun on the Earth holds the Earth in an orbit around the Sun. Let us assume that the orbit is perfectly circular. The work done by this gravitational force during a short time interval in which the Earth moves through a displacement in its orb...
Effects of changing orbital velocity of Earth on its orbit The Sun, given how mind-bogglingly massive it is, exerts a strong gravitational force on every member of the solar system, including Earth. Therefore, a high orbital velocity is the only thing that keeps us from crashing ...
