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.

How to calculate the time it takes for an object to fall on a curved path?
My answer is quite late, but I hope someone will find it helpful.
In fact, we can use Newtonian mech to solve this problem.
We first decompose the gravitational force into two components--tangential a …

Why do satellites orbit around the centre of a planet?
If we ignore the cases of elliptical orbits, the earth gives the satellite a gravitational attraction towards its centre, which is perpendicular to the velocity of the satellite. In your question, suc …
