Menu images of the Gravity and Orbits simulation. 1 Click the PLAY button and describe what you see.Explanation / Answer
1) Due to gravitation force between earth and sun Earth is rotating around the sun as this force acts as the centripetal force which gives a rotation
2) On increasing either mass the orbit of rotation becomes elliptical whenever the earth is near to three sun it moves faster in order to keep the areal velocity constant.
5) If mass of planet is large compared to sun then it may leave the orbit. Or we can say that mass of sun should be less.
6) Yes now if mass of sun becomes too large then the planet will fall into the sun as increase in mass keeping volume constant will increase density which increases gravity.
8) The planet orbit won't change but monm will have something spiral kind of shape around the planet.
9) Increasing planet mass and decreasing sun mass will make the moon to fall in sun and planet orbit increase as usual.
Part 2
1) The orbit is circular with mass of sun to be 333 Times than the earth.
2) The orbit changes as in earlier part.
