FORCE AND WEIGHTApplication of Newton's LawsCP-04 Page 4Rev. 0Force and Weight Summary+Force is a vector quantity that tends to produce an acceleration of a bodyin the direction of its application.orF = ma+Weight is the force exerted on an object due to gravity. (On the earth it isthe gravitational pull of the earth on the body.)W = mg/gcWith the idea of mass and weight understood, especially their differences, the concept ofgravitational force is more easily explained. Any object that is dropped will accelerate as it falls,even though it is not in physical contact with any other body. To explain this, the idea ofgravitational force was developed, resulting in the concept that one body, such as the earth, exertsa force on another body, even though they are far apart. The gravitational attraction of two objectsdepends upon the mass of each and the distance between them. This concept is known as Newton'slaw of gravitation, which was introduced in an earlier chapter.SummaryThe important concepts of force and weight are summarized below.
