Course Outline


Cambridge AS and A level Syllabus at GEMS Wesgreen International School aims to provide the students an opportunity to develop attitudes relevant to physics such as; concern for accuracy and precision, objectivity and inquiry. Cambridge International AS and A Level Physics helps learners develop the knowledge and skills that will prepare them for successful university study.

Learning Outcomes

Students should be helped to understand how, through the ideas of physics, the complex and diverse phenomena of the natural world can be described in terms of a number of key ideas which are of universal application and which can be illustrated in the separate topics set out below. These ideas include:

  • the use of models, as in the particle model of matter or the wave models of light and of sound
  • the concept of cause and effect in explaining such links as those between force and acceleration, or between changes in atomic nuclei and radioactive emissions
  • the phenomena of ‘action at a distance’ and the related concept of the field as the key to analysing electrical, magnetic and gravitational effects
  • that differences, for example between pressures or temperatures or electrical potentials, are the drivers of change
  • that proportionality, for example between weight and mass of an object or between force and extension in a spring, is an important aspect of many models in science.

Ongoing Objectives

Throughout each unit, the students are given the opportunity to build on the objectives below:

  • provide an enjoyable and worthwhile educational experience for all learners, whether or not they go on to study science beyond this level.
  • enable learners to acquire sufficient knowledge and understanding to:
  • become confident citizens in a technological world and develop an informed interest in scientific matters
  • allow learners to recognize that science is evidence-based and understand the usefulness, and the limitations, of scientific method
  • develop skills that:
  • are relevant to the study and practice of physics
  • are useful in everyday life
  • encourage a systematic approach to problem-solving
  • encourage efficient and safe practice
  • encourage effective communication through the language of science
  • develop attitudes relevant to physics such as:
  • concern for accuracy and precision
  • objectivity
  • integrity
  • enquiry
  • initiative

Unit Overviews

Term 1

For blended learning we will provide video links, live demonstrations of practical investigation as well as access to the relevant worksheets and resources that all students will need.

The principles of circular motion are relevant to many areas of physics, and in particular to the orbits of satellites and moons around planets, and to the movement of charged particles in magnetic fields, so it is important to teach this unit before moving on later to Unit 18 and Unit 21. The study of circular motion follows on from and builds on previous work on linear motion and acceleration. They study some of the many examples of naturally occurring oscillations, and the unit is closely linked to circular motion. The qualitative and quantitative concepts concerning the states of matter, changes of state and internal energy are fundamentally important in developing an understanding of the behavior of matter in the world around us.

  • explain how electric and magnetic fields can be used in velocity selection.
  • explain the forces between current-carrying conductors and predict the direction of the forces.
  • recall and solve problems using Faraday’s law of electromagnetic induction and Lenz’s law.
  • explain simple applications of electromagnetic induction.

Term 2

Programme of Study 


Formative: Throughout the units, the students will complete graded work, quizzes and practical, research activities, which allows the teacher to assess the students’ attainment and inform their planning.

For each unit the students complete a pre and posttest. This allows us to see progress across the units and to inform our planning.

Summative: At the end of first term we complete internal tests – Unit based and combined Units. Students complete standardized tests such as Mock Exam during the month of March. This allows us to measure the students’ progress throughout the term and year.
