New Value for Gravitational Constant Could Blow Our Minds.
Derived Value for a Universal Gravitation Constant for Pushing Gravity Assumptions. Gravity comes from outer space and pushes. Gravity is streams of particles travelling in straight lines. Figure 1. Taking the earth as a sphere and placing a sphere of 1kg mass on the earth's surface, the centre of the imaginary sphere is where the two spheres touch and gravity from one side of the imaginary.
The acceleration due to gravity near the Earth depends on the distance of an object from Earth's center. The gravitational field formula can be used to find the field strength, meaning the acceleration due to gravity at any position around the Earth. The radius of the Earth is, and so values of r in the formula are (typically) greater than this radius. The gravitational field strength is.
Then we can simply turn Kepler's Third Law around to solve for the value of k: Exercise: What is the value of the Gaussian gravitational constant k? The key point here is that the only measured quantity we need to find k is time: the period of the Earth's orbit around the Sun. Now, it's not quite so easy as it sounds, but it can be done without.
The latest measurement of G, the so-called constant that puts a figure on the gravitational attraction between two objects, has come up higher than the current official value.
Each of the really fundamental force laws of nature is very general, and needs to be linked to our own particular universe by measuring the value of a universal constant embedded in the law. In the case of Newton it is G, the gravitational constant (as distinct from g which is merely the acceleration at the surface of the Earth and so of local interest only).
Assuming both gravitational forces depend on the same G constant, the tilted angle of the string would give you the relation between the mass of the mountain and the mass of the Earth (the rest of.
