Gravitation Gravitation is the attraction between objects that have mass. Newton's law states: The gravitational attraction force between two point masses is directly proportional to the product of their masses and inversely proportional to the square of their separation distance.

Divergence of a radial 1 / r 2 vector field Ask Question Asked 9 years, 3 months ago Modified 6 years, 1 month ago Viewed 5k times 2 How to obtain the divergence of the function F(r, ฯ, ฮธ) = หr / r2 where หr is the unit vector in radial direction? Is there a solution without computing the surface integral for definition of divergence?

The distance square in the Newton's law of universal gravitation is really a square? (7 answers) Closed 9 years ago. Is there something intrinsic about the structure of space that gravity is proportional to 1/r^2 instead of, for example, 1/r^2.143 ? What makes the exponent turn out to be a nice even number? newtonian-gravity Share Cite

Here are some basic characteristics of the measure: Since r 2 is a proportion, it is always a number between 0 and 1.; If r 2 = 1, all of the data points fall perfectly on the regression line. The predictor x accounts for all of the variation in y!; If r 2 = 0, the estimated regression line is perfectly horizontal. The predictor x accounts for none of the variation in y!

The coefficient of determination or R squared method is the proportion of the variance in the dependent variable that is predicted from the independent variable. It indicates the level of variation in the given data set. The coefficient of determination is the square of the correlation (r), thus it ranges from 0 to 1.

You can find the gradient of $1/r$ more easily using the chain rule and the identity $\nabla r^2 = 2 \vec r$. In particular, $$\nabla \frac{1}{r} = \nabla \frac{1}{\sqrt{r^2}} =- \frac{1}{2 (r^2)^{3/2}} \nabla r^2 =-\frac{\vec r}{ r^3} = -\frac{\hat r}{r^2}$$ Finally, in evaluating the problem $\nabla \cdot \hat r$, you can use the product rule:

Massless photon case: Now, the 1 / r potential gives rise to a force that goes as 1 / r 2. This force decreases as the area of the sphere of radius r, indicating that the force 1 / r 2 is a purely geometrical fact of 3 spatial dimensions: intuitively, we emit N photons from a point and the force decreases with the surface density of the photons.

The " coefficient of determination " or " R-squared value ," denoted R 2, is the regression sum of squares divided by the total sum of squares. Alternatively (as demonstrated in the video below), since SSTO = SSR + SSE, the quantity R 2 also equals one minus the ratio of the error sum of squares to the total sum of squares:
