Variation of g due to height and depth - comparative study ...

Variation of g with height: As altitude or height h increases above the earth's surface the value of acceleration due to gravity falls. This is expressed by the formula g1 = g (1 – 2h/R). Here g1 is the acceleration due to gravity at a height of h with respect to the earth's surface and R is the radius of the earth.

Newton's Law of Universal Gravitation | Boundless Physics

Universal Gravitation for Spherically Symmetric Bodies. The Law of Universal Gravitation states that the gravitational force between two points of mass is proportional to the magnitudes of their masses and the inverse-square of their separation, [latex]text{d}[/latex]: [latex]displaystyle text{F}=frac{text{GmM}}{text{d}^2}[/latex] However, most objects are not point particles.

Gravity - Wikipedia

Gravity (from Latin gravitas 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energy, including planets, stars, galaxies and even light, are attracted to (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the tides of the oceans. The gravitational attraction of the original gaseous matter ...
