by EAEP
Certificate Physics is a four-year course developed for use in Secondary Schools. The course is written in line with the new Kenyan Syllabus (2002) and covers all the outlined topics. It has been developed with both the student’s and the teacher’s needs in mind. It draws heavily from the local environment, especially the available resources. The student-centred approach used in the course will enhance the learning of Physics at this level and beyond.
This is the fourth book in this series and is meant for use in Form Four. It is written using simple language, and it is well illustrated with clearly worked examples. There are clearly guided experiments meant to create and sustain interest in learning of Physics.
