Mastering these areas will prepare you well for whatever questions appear on the exam and set you up for success in your university physics courses.

Mechanics (Forces, Newton’s Laws, Energy, Momentum, Rigid Body Dynamics)

As a physics student preparing for the JAMB exam, a solid understanding of mechanics is essential. This area of concentration covers forces, Newton’s laws of motion, energy, momentum, and rigid body dynamics.

  • Forces: A force is any interaction that, when unopposed, will change the motion of an object. The four fundamental forces are gravitational, electromagnetic, strong nuclear, and weak nuclear forces. Forces are measured using the SI unit called the newton (N).
  • Newton’s Laws: Sir Isaac Newton proposed three laws of motion in his work Philosophiæ Naturalis Principia Mathematica. The first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The second law focuses on the relationship between an object’s mass, its acceleration, and the applied force. The third law states that for every action, there is an equal and opposite reaction.
  • Energy and Momentum: The total energy of a system is conserved, meaning it remains constant. Energy comes in many forms, including kinetic, potential, thermal, light, sound, and chemical. Momentum is the quantity of motion of an object and is equal to the mass times the velocity. Like energy, the total momentum of a system is conserved.
  • Rigid Body Dynamics: A rigid body is an idealization of a solid body of finite size in which deformation is neglected. Rigid body dynamics deals with the motion of rigid bodies under the action of forces. Concepts such as center of mass, linear and angular momentum, torque, and rotational kinetic energy are studied.

In summary, mechanics provides a foundation for understanding motion and its causes. Mastery of these concepts will prepare you well for the JAMB physics exam.

Thermal and Statistical Physics (Temperature, Heat, Work, Kinetic Theory, Entropy, First and Second Laws of Thermodynamics)

As a physics student preparing for the JAMB exam, a solid understanding of thermal and statistical physics is essential. This area of concentration focuses on concepts such as:

  • Temperature: The measure of the average kinetic energy of particles in matter. Measured in units such as Kelvin, Celsius and Fahrenheit.
  • Heat: The transfer of thermal energy between systems at different temperatures. Heat will always flow from a system at higher temperature to one at lower temperature. Methods of heat transfer include conduction, convection and radiation.
  • Work: The amount of energy transferred by a force acting through a distance. Measured in joules (J). Work and heat are the two main ways to change the internal energy of a system.
  • Kinetic theory: Explains the behavior of gasses in terms of the motion of molecules. Key concepts are that molecules in a gas are in constant random motion and collisions between molecules are elastic.
  • Entropy: A measure of the amount of disorder or randomness in a system. The second law of thermodynamics states that the total entropy of an isolated system always increases over time and approaches a maximum value.
  • Laws of thermodynamics: The first law states that the total energy of an isolated system is conserved. The second law states that the total entropy of an isolated system always increases over time. These laws govern the flow and conversion of energy in the universe.

By understanding these fundamental concepts and relationships in thermal and statistical physics, you will build a solid foundation to tackle many questions on the JAMB exam. Be sure to also study worked examples to see how these concepts are applied to solve problems. With diligent preparation, you can master this area of concentration.

Waves and Optics (Wave Phenomena, Sound Waves, Light Waves, Geometrical Optics, Physical Optics, Interference, Diffraction)

Wave Phenomena

As a form of energy transfer, waves are fundamental to many areas of physics. Wave phenomena, including propagation, reflection, refraction, diffraction, interference, and polarization, demonstrate how waves travel, interact with matter, and interact with each other.

Sound Waves

Sound waves are longitudinal mechanical waves that travel through a medium, like air or water. They are created by vibrations and result in the transmission of energy through the propagation of pressure variations. The speed of sound depends on the properties of the medium, such as density and compressibility.

Light Waves

Visible light is a small portion of the electromagnetic spectrum, which includes radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. Light waves exhibit properties of both particles and waves. They can be described by frequency, wavelength, amplitude, and speed. Light waves travel at 3 x 108 m/s in a vacuum.

Geometrical Optics

Geometrical optics describes light propagation in terms of rays. It is used to analyze reflection and refraction at plane and curved surfaces, as well as image formation using mirrors and lenses. Reflection follows the law of reflection, with the angle of incidence equaling the angle of reflection. Refraction follows Snell’s law, with the refractive index determining how much the ray is bent.

Physical Optics

Physical optics considers the wave nature of light. It is used to analyze interference, diffraction, polarization, and other wave phenomena. Interference occurs when multiple waves combine, resulting in increased or decreased amplitude. Diffraction describes the bending and spreading of waves around obstacles or through apertures. Polarization refers to the orientation of the electric field vector in an electromagnetic wave.

In summary, understanding waves and optics provides a foundation for many areas of physics and technology. Mastering the concepts and mathematics behind wave phenomena and the properties of light enables a deeper comprehension of the world around us.

Electricity and Magnetism (Electrostatics, Current Electricity, Magnetism, Electromagnetic Induction, Alternating Current, Electromagnetic Waves)

As an area of concentration in Physics, Electricity and Magnetism is fundamental to understanding the physical world around us. This field of study focuses on the forces between electric charges and the relationship between electricity and magnetism.


Electrostatics deals with electric charges at rest and the forces between them. Key concepts include:

  • Coulomb’s law: The force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
  • Electric field: The field of force surrounding a charged particle that exerts a force on other charged particles.
  • Gauss’s law: The electric flux through any closed surface is proportional to the enclosed electric charge.

Current Electricity

Current electricity involves the flow of electric charge through a medium. Key principles include:

  1. Ohm’s law: The current through a conductor is directly proportional to the potential difference across it, provided temperature remains constant.
  2. Kirchhoff’s laws: The sum of currents entering a junction equals the sum of currents leaving it (conservation of charge). The sum of potential differences in a closed circuit is zero (conservation of energy).
  3. Resistance: A measure of how much a material opposes the flow of electric current. Resistance causes energy to be dissipated as heat.


Magnetism arises from the motion of electrons, which are tiny charged particles. Key ideas include:

  • Magnetic fields: The region around a magnet where its magnetic force is exerted.
  • Magnetic force: The force exerted by a magnetic field on other magnets and magnetic materials.
  • Ferromagnetism: The mechanism by which certain materials can become magnetized and attract other magnetic materials.

Electromagnetic Induction

Electromagnetic induction is the generation of an electric current by a changing magnetic field. Key principles include:

  • Faraday’s law of induction: The induced electromotive force in a closed circuit is equal to the negative of the rate of change of magnetic flux through the circuit.
  • Lenz’s law: The direction of the induced current is always such that it opposes the change producing it.

Modern Physics (Special Relativity, Quantum Theory, Atomic Structure, Nuclear Physics, Solid State Physics, Particle Physics, Relativity)

As a physics student preparing for the JAMB exam, having a strong grasp of modern physics concepts is essential. This area of concentration covers some of the most important discoveries and theories of the 20th and 21st centuries.

Special Relativity

Proposed by Albert Einstein in 1905, the theory of special relativity revolutionized our understanding of space and time. Some of its core ideas are:

  • The speed of light is constant: Light always travels at 670 million miles per hour in a vacuum.
  • Time dilation: Time passes more slowly for someone moving at very high speeds relative to others.
  • Length contraction: Objects appear contracted along the direction of motion at very high speeds.
  • Mass-energy equivalence: Einstein’s famous equation, E=mc2, shows that energy and mass are equivalent and can be changed into each other.

Quantum Theory

The quantum theory describes the behavior of matter and energy at the molecular, atomic, nuclear, and even smaller microscopic levels. Some key concepts include:

  1. Quantization: Energy, angular momentum, and other physical properties are restricted to discrete values.
  2. The Heisenberg Uncertainty Principle: We cannot know the position and momentum of a particle simultaneously with infinite precision.
  3. Wave-particle duality: Matter and light exhibit properties of both particles and waves.
  4. Quantum superposition: Quantum objects can exist in a superposition of multiple states until measured.

Atomic Structure

The quantum theory led to a new model of the atom with electrons in discrete energy levels. The Bohr model of the atom, with electrons orbiting the nucleus in quantized orbits, has been supplanted by the quantum mechanical model where electrons occupy probability distributions around the nucleus.

Modern physics has revolutionized our understanding of space, time, and the physical world. The concepts and theories discussed here form the foundation of many areas of physics and technology today. Studying them will prepare you well for university-level physics.
