Application of Newton's LawsFORCE AND WEIGHTRev. 0Page 1CP-04FORCE AND WEIGHTForce can be thought of simply as a push or pull, but is more clearly defined asany action on a body that tends to change the velocity of the body. Weight is aforce exerted on an object due to the object's position in a gravitational field.EO 1.1DEFINE the following:a.Forceb.WeightIntroductionIn the study of forces, the student must make valid assumptions called for in the formulation ofreal problems. The ability to understand and make use of the correct assumptions in theformulation and solution of engineering problems is certainly one of the most important abilitiesof a successful operator. One of the objectives of this manual is to provide an opportunity todevelop this ability through the study of the fundamentals and the analysis of practical problems.An effective method of attack on all engineering problems is essential. The development of goodhabits in formulating problems and in representing their solutions will prove to be a valuable asset.Each solution should proceed with a logical sequence of steps from hypothesis to conclusion, andits representation should include a clear statement of the following parts, each clearlydefined: a) given data, b) results desired, c) necessary diagrams, d) calculations, and e) answersand conclusions. Many problems become clear and straightforward once they are begun with alogical and disciplined method of attack.In addition, it is important to incorporate a series of checks on the calculations at intermediatepoints in the solution. Also, all work must be neat and orderly.The subject of classical physics is based on surprisingly few fundamental concepts and involvesmainly the application of these basic relations to a variety of situations. Newton's laws of motionare some of the fundamental concepts used in the study of force and weight.
