Physics is often seen as the most important of the natural sciences. It involves studying matter, energy, and the basic forces that shape the universe. This field is the basis for many technological advances and helps us understand how the world works.

Studying Physics in SS2 (Senior Secondary School Year 2) using the Lagos State Unified Scheme of Work is a key part of Nigerian students’ education and personal growth. SS2 is a crucial year where students build on the basics they learned in SS1 and start exploring more complex and abstract ideas.

A good understanding of Physics in SS2 is important for students who want to go on to higher education in fields like engineering, medicine, computer science, and environmental science. The Lagos State unified scheme of work prepares students well for important national exams like the West African Senior School Certificate Examination (WASSCE) and the Unified Tertiary Matriculation Examination (UTME), which are necessary for getting into universities and colleges.

At the end of the SSS2 session, students can;

- Define projectiles and derive the various equations associated with it;
- Describe equilibrium and distinguish between the various types;
- Define machines; identify the types and their corresponding velocity ratios;
- Determine latent heat and specific heat capacity of various substances;
- Distinguish between evaporation and boiling as well as saturated vapour pressure and unsaturated vapour pressure;
- State the law of linear momentum and use it to solve problems;
- Analyse the concept of Simple Harmonic Motion (SHM);
- State and experimentally verify the gas laws;
- Define waves, identify the types, and distinguish between the various properties;
- Explain how light is refracted through rectangular prisms, glass blocks, and lenses;
- Describe the mode of function of optical instruments;
- Identify eye defects and their various corrections;
- Explain vibrations in pipes and strings.

Assessment methods for Physics in SS2 in Nigeria include continuous assessment through tests and homework, practical experiments and reports, project-based assessments, written exams, and oral presentations. These varied methods ensure comprehensive evaluation, fostering students’ understanding, critical thinking, problem-solving, and preparation for national exams.

Grading follows a scale from A to F, with A representing excellent performance, typically scoring around 70% or 80%, and F indicating failure, usually below 50% or 45%.
