Statics is the action of one body on another. A force is either a push or a pull. A force tends to move a body in the direction of its action. The action of a force is characterized by its magnitude, by the direction of its action, and by its point of application. Thus, force is a vector quantity, because its effect depends on the direction as well as on the magnitude of the action. Forces are classified as either contact or body forces. A contact force is produced by direct physical contact; an example is the force exerted on a
AS 314 AS 314 AS 314, also known as V452 Scuti, is a white hypergiant star and luminous blue variable candidate located in the constellation of Scutum. It has an apparent magnitude of 9.85 and can be seen with small telescopes. AS 314 was poorly studied until the year 2000, when Miroshnichenko et al. determined a distance for this star of around 10 kiloparsecs (32,600 light years), a luminosity 160,000 times that of Sun (), a radius 200 times the solar radius (), and an initial mass of 20 solar masses (). It's losing each year (in other words, every 50,000 years)
