Physics Lesson Note For SS3(First Term)
Below are the 2022 complete Physics lesson notes for SS3 First Term
Week 1 – Waves
Overview – There are mechanical waves and there are electromagnetic waves. Mechanical waves are waves that require a material medium for their propagation while electromagnetic waves are waves that do not require a material medium for propagation. When the waves of the magnetic and electric fields combine and are mutually at right angles to each other, electromagnetic (EM) waves arise. This week, we shall learn about waves – electromagnetic waves and the electromagnetic spectrum which refers to the entire range of electromagnetic waves. We shall also learn about the uses of the types of waves that make up the electromagnetic spectrum. To learn more, Click here…
Week 2 – Energy and society
Overview – In human society, the term “energy” is synonymous to energy resources. Man uses these energy resources to carry out activities such as heating up homes, power transportation, etc. There are several sources of energy which have been classed into renewable (can be replenished) and non-renewable sources of energy (cannot be replenished). Examples of sources of energy include solar, nuclear, wind, geothermal energy and so on. These energy sources are very beneficial to man but they can also be harmful to man and the environment. This week, we shall learn about energy sources – their uses and impact on the development of a nation. We shall also learn about some energy concepts such as energy conservation, energy diversification and energy crisis. To learn more, Click here…
Week 3 – Properties of wave
Overview – All waves have the properties – of reflection, refraction, diffraction and interference. When waves travel to the end of a medium, they do not just stop, rather they show these properties. Diffraction is a property of waves that involves the ability of waves to bend around obstacles in their path or pass through small openings. Interference occurs when two waves occupy the same space at the same time and it brings about the principle of superposition. This week, we shall learn about the properties of waves – diffraction and interference (of light and sound waves). We shall also learn about the polarization of light. Polarization is a phenomenon whereby a wave whose vibrations are only in one plane is polarized. Only transverse waves can undergo polarization. To learn more, Click here…
Week 4 – Gravitational field
Overview – Gravitational field is a region or space around a mass in which the gravitational force of the mass can be felt. The earth exerts a gravitational force that attracts objects to the centre of the earth. This week, we shall learn about the gravitational field. We shall also learn about escape velocity which describes the minimum velocity needed by an object so that it can escape the gravitational influence of an astronomical body permanently.

Week 5 – Electric Field
Overview – Electric field is a region where a charged body experiences an electric force. This week, we shall learn about the electric field and Coulomb’s law. To learn more, Click here…
Week 6 – Concept of electric field
Overview – This week, we shall learn more about the electric field, capacitors, an electronic device for storing charge and capacitance as well as the arrangement of capacitors (series and parallel). To learn more, Click here…
Week 7 – Current electricity
Overview – Current electricity is the steady flow of electrons. A continuous flow of charges is produced from the primary and secondary cell. Primary cells are those from which current is produced as a result of non-reversible chemical changes while secondary cells are cells whose chemical actions can be reversed. This week, we shall learn about current electricity (from primary and secondary cells). We shall also learn about some examples of primary and secondary cells. To learn more, Click here…
Week 8 – Electrical energy and power shunt and multiplier, resistivity and conductivity
Overview – This week, we shall dive even deeper into the concept of the electric field. We shall learn about basic electric measurements – resistivity and many more. To learn more, Click here…

Week 9 – Magnetic field
Overview – Magnetic field has a region around a magnet in which the influence of the magnet can be felt or detected. Magnets are objects that produce magnetic fields. They have both North and South poles. This week, we shall learn about the magnetic field, how magnets can be formed, demagnetization and the earth’s magnetic field. To learn more, Click here…
Week 10 – Electromagnetic field
Overview – Electromagnetic field is a field representing the joint interaction of electric and magnetic fields. It is a property of space caused by the motion of an electric charge and it exerts a force on charged particles. This week, we shall learn about the electromagnetic field. To learn more, Click here…
Week 11 – Simple A.C. circuits
Overview – A.C. is an abbreviation for alternating current. A.C. circuits allow alternating currents to flow through them. They applied for several purposes such as power transmission, medicine, telecommunication, etc. This week, we shall learn about A.C. circuits. To learn more, Click here…
Week 12 – Examination
Overview – This week, there will be a revision on all the topics covered this term, from waves to simple A.C. circuits. We shall also be examined all we have learned this term.
Week 13 – Examination
Overview – This week, we shall be examined all we have learned this term.
