tips for preparation for WAEC/NECO practical physics examination
There are three major area on consistent basics Waec/Neco has been examining the scientific skills in students.They are: Mechanics, Optics, Electricity we have other areas ,but is just once in a while we have questions coming from it e.g heat, sound wave Few topics in the major area WAEC/NECO on regular basics bring out practical questions from are: 1.Mechanics practical - Pendulum bob experiment (Simple Harmonic Motion) - Moment of forces - Parallelogram law of vectors - Hooke’s law - Upthrust - Relative density - Friction Apparatus: Retort stand, boss head, Meter rule (100cm), Stop clock, Thread, Slotted masses, Beaker, Water, Kerosene, Pendulum Bob, Stool/Table, G-clamp, F –clamp, Rough surfaces. 2.OPTICS PRACTICAL - Ray box experiment - Mirror experiment (Reflection) - Rectangular glass block (refraction) - Triangle prism (refraction) Apparatus: Ray box, concave lens, convex lens of focal length between 15cm-20cm, Screen, Meter rule, Rectangular gl
