Downloaded from www.campusportal.com.ng PHYSICS PREAMBLE The syllabus is evolved from the Senior Secondary School teaching syllabus and is intended to indicate the scope of the course for Physics examination. It is structured with the conceptual approach. The broad concepts of matter‚ position‚ motion and time; energy; waves; fields; Atomic and Nuclear Physics‚ electronics are considered and each concept forms a part on which other subconcepts are further based. AIMS The aims of the syllabus are to enable candidates

Designing a roller-coaster is not easy‚ they have to be thrilling and exciting but not jerky. A lot of work has to be done to design a safe yet breathtaking roller coaster. The engineers have to consider the forces acting on the roller coaster train as they gain momentum and the structural support needed to support these forces. There are different designs of a roller coaster‚ for example‚ a suspended roller coaster‚ in which the track is above the speeding car. There are wooden‚ regular steel‚ steel-flying

Problems and Solutions in Elementary Physics by C. Bond The following sections include solutions to a number of my favorite problems in elementary physics. Some of the solutions bear aspects resembling that of a magician pulling a rabbit out of a hat. Others simply demonstrate the remarkable power of a few seminal concepts to reveal the inner workings of the real world. Most of the problems yield to solution strategies other than the ones shown‚ but these represent my own preference. At some point

Brian Thomas‚ The Ohio State University‚ Columbus‚ Ohio ture of a vibratory bowl feeder is the maximum speed at which it can convey parts. Though not the first to research vibratory feeders‚ he worked independently of other investigators to develop a basic theory of operation. He defined the essential parameters for bowl analysis and with these defined the

acting as the centripetal force in this lab is tension‚ which is caused by gravity. Fg= mg. Fg= 1.05 N. The speed varies with the radius of the string. The larger the radius‚ the slower the speed. My hypothesis was incorrect. Although the time got longer‚ the speed also increased making it faster as the radius increased. According to my data‚ speed and radius have a direct relationship. Speed and Centripetal Force Question What is the relationship between centripetal force and the

Force: This can be defined as a pushing or pulling action that causes a change of the state of a body. A long jumper who wants to increase their degree of force will need to increase their weight‚ but this can negatively affect their speed‚ so it is vital to get the balance right. The law of reaction also applies to movements that occur in the air. In these situations the equal and opposite reaction is shown in movements of other parts of the body. A long jumper‚ for example‚ will bring the arms
