This tag is for questions regarding the Newtonian model of gravity in which the force between two objects is given by $~GMm/r^2~.$ It is a natural phenomenon by which all things with mass or energy – including planets, stars, galaxies, and even light – attract one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.

Are we slightly lighter during the day and slightly heavier at night, owing to the force of ...
Setting aside tidal force. Distance to sun aprox. 150*10^9m +(-)637*10^3m ,and since earth(masspoint) always in free fall it makes on average 0.006m/s2*(150E9m+637e3m)^2/(150E9m-637E3m)^2 -0.006m/s2 = …
