About PHYSICS

Physics is a field of natural science that concentrates on the study of matter, including its fundamental components, motion, and behavior both in space and time, in addition to the associated concepts of energy and force.

Physics has alot of definition which differs as a result of source but know that every definition still have the same meanig or pass the same information. Some of the world great Physicists are: Albert Einstein, Isaac Newton, Galileo Galilei, Richard Feynman, Micheal Faraday, Marie Curie. Some are even known as father of physics and some father of modern physics.

Important Topics In PHYSICS

Physics is one of the important subjects you have to pass as a science student. Physics covers many topics such as: waves, electric current, thermodynamics, electrostatics, optics, kinetics theory of gases, rotational motion, sound, atom, electromagnetism, mechanics, work, atomic structure, geometrical optics, vectors, projectiles, kinematics. Remember for you to pass NECO, you have to treat important topics, so here are the important topics in Physics needed to pass NECO:

  • Measurement and Units
  • Scalars and Vectors
  • Motion
  • Gravity
  • Equilibrium of Forces
  • Work, Energy and Power
