HIDDEN FACTS IN PHYSICS

Hidden Facts in SSCE Physics covers the entire SSCE Physics Syllabus including Practical and Alternative to Practical. The notes, examples and exercises were presented in line with the expectations of the examiners from students and the current trend of the examination.The current expectation of the examiners is that the answers should be brief and straight to the point. However for the fact that Hidden Facts in SSCE Physics is a teach – yourself series, many of the solutions to questions are a bit longer. The purpose is to give the average student a clear understanding even when there is no teacher to guide him/her.

In many cases, additional notes are added to the solutions to explain some hidden facts/concepts. Such notes are indicated as not part of the solution. In some cases the notes are instructions and warnings that the students need to adhere to, so as not to lose marks.

In calculation problems, the general trend/expectation is :

- Stating the formula/equation connecting the given/hidden data.

- Solving for the hidden data ( if any).

- Substituting into the connecting equation.

- Evaluating to obtain the required quantity.

You may solve for the hidden data before stating the connecting formula.

The notes on Practical Physics address the challenges that Students usually face in a Physics Practical Examination.
