To Kill a Mockingbird is a 1962 American coming-of-age legal drama crime film directed by Robert Mulligan starring Gregory Peck and Mary Badham, with Phillip Alford, John Megna, Frank Overton, James Anderson, and Brock Peters in supporting roles. It marked the film debut of Robert Duvall, William Windom, and Alice Ghostley.
In particular, starlight is deflected as it passes near the Sun, leading to apparent shifts of up to 1.75 arc seconds in the stars' positions in the sky (an arc second is equal to 1/3600 of a degree). In the framework of Newtonian gravity, a heuristic argument can be made that leads to light deflection by half that amount.
A common misconception occurs between centre of mass and centre of gravity.They are defined in similar ways but are not exactly the same quantity. Centre of mass is the mathematical description of placing all the mass in the region considered to one position, centre of gravity is a real physical quantity, the point of a body where the gravitational force acts.
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.
To Kill a Mockingbird is a novel by the American author Harper Lee. It was published in July 1960 and became instantly successful. In the United States, it is widely read in high schools and middle schools. To Kill a Mockingbird won the Pulitzer Prize a year after its release, and it has become a classic of modern American literature.
In classical mechanics, a gravitational field is a physical quantity. [5] A gravitational field can be defined using Newton's law of universal gravitation. Determined in this way, the gravitational field g around a single particle of mass M is a vector field consisting at every point of a vector pointing directly towards the particle. The ...

Le Sage's theory of gravitation is a kinetic theory of gravity originally proposed by Nicolas Fatio de Duillier in 1690 and later by Georges-Louis Le Sage in 1748. The theory proposed a mechanical explanation for Newton's gravitational force in terms of streams of tiny unseen particles (which Le Sage called ultra-mundane corpuscles) impacting all material objects from all directions.
