WAEC 2019/2020 Physics Syllabus Questions and Answers

So many waec candidates have been asking questions about 2019 physics waec syllabus and topics to read so as to pass waec Physics 2019 without much stress. The truth of the matter is that, the relevance of Jamb syllabus and expo on the topics to focus on cannot be overemphasised. There are four weapons you need you need to pass the WAEC 2019/2020 examination. They are: WAEC Syllabus WAEC past questions and answers Hot topics to read to pass waec 2019 The recommended waec textbooks and Your complete preparation. In this article, I will break down the waec physcis syllabus for you. WEST AFRICAN SENIOR SCHOOL CERTIFICATE EXAMINATION WAEC PHYSICS SYLLABUS 383 SECTION A FOR CANDIDATES IN ALL MEMBER COUNTRIES PART I MATTER, POSITION, MOTION AND TIME TOPICS NOTES 1. Concepts of matter 2. Fundamental and derived quantities and units (a) Fundamental quantities and units (b) Derived quantities and unit 3. Position, distance and displacement. (a) Concept of position as a location of point – rectangular coordinates. (b) Measurement of distance (c) Concept of direction as a way of locating a point – bearing (d) Distinction between distance and displacement Simple structure of matter should be discussed. The three states of matter, namely solid, liquid and gas. Evidence of the particle nature of matter e.g. Brownian motion experiment, Kinetic theory of matter. Use of the theory to explain: states of matter (solid, liquid and gas), pressure in a gas, evaporation and boiling; cohesion, adhesion, capillarity. Crystalline and amorphous substances to be compared (Arrangement of atoms in crystalline structure not required.) Length, mass, and time as examples of fundamental quantities and m, kg and s as their respective units. Volume, density and speed as derived quantities and m3, kgm-3 and ms-1 as their respective units. Position of objects in space using the X,Y,Z axes can be mentioned. Use of string, metre rule, vernier callipers and micrometer screw gauge. Degree of accuracy should be noted. Metre (m) as unit of distance. Use of compass and a protractor. Graphical location and directions by axes to be stressed. WEST AFRICAN SENIOR SCHOOL CERTIFICATE EXAMINATION PHYSICS SYLLABUS 384 TOPICS NOTES 4. Mass and weight Distinction between mass and weight 5. Time (a) Concept of time as interval between physical events (b) Measurement of time 6. Fluids at rest (a) Volume, density and relative density (b) Pressure in fluids (c) Equilibrium of bodies (i) Archmedes’ principle (ii) Law of flotation Use of lever balance and chemical/beam balance to measure mass and spring balance to measure weight. Kilogram (kg) as unit of mass and newton (N) as unit of weight. The use of heart-beat, sand-clock, ticker- timer, pendulum and stopwatch/clock. Seconds (s) as units of time. Experimental determination for solids and liquids. Concept and definition of pressure. Pascal’s principle, application of principle to hydraulic press and car brakes. Dependence of pressure on the depth of a point below a liquid surface. Atmospheric pressure. Simple barometer, manometer, siphon, syringes and pumps, determination of the relative density of liquids with U-tube and Hare’s apparatus. Identification of the forces acting on a body partially or completely immersed in a fluid. Use of the principle to determine the relative densities of solids and liquids. Establishing the conditions for a body to float in a fluid. Applications in hydrometer, balloons, boats, ships, submarines etc. WEST AFRICAN SENIOR SCHOOL CERTIFICATE EXAMINATION PHYSICS 385 TOPICS NOTES 7. Motion (a) Types of motion: Random, rectilinear, translational, rotational, circular, orbital, spin, oscillatory (b) Relative motion (c) Cause of motion (d) Types of force: (i) Contact force (ii) Force Field (e) Solid friction (f) Friction in fluids (Viscosity) (g) Simple ideas of circular motion Only qualitative treatment is required. Illustration should be given for the various types of motion. Numerical problems on co-linear motion may be set. Force as cause of motion. Push and pull Electric and magnetic attractions and repulsion; gravitational pull. Frictional force between two stationary bodies (static) and between two bodies in relative motion (dynamic). Coefficients of limiting friction and their determination. Advantages of friction e.g. in locomotion, friction belt, grindstone. Disadvantages of friction e.g. reduction of efficiency, wear and tear of machines. Methods of reducing friction. Use of ball bearings, rollers and lubrication. Definition and effects. Simple explanation as extension of friction in fluids. Fluid friction and its application in lubrication should be treated qualitatively. Terminal velocity and its determination. Experiments with a string tied to a stone at one end and whirled around should be carried out to (i) demonstrate motion in a vertical/horizontal circle. WEST AFRICAN SENIOR SCHOOL CERTIFICATE EXAMINATION PHYSICS 386 TOPICS NOTES 8. Speed and velocity (a) Concept of speed as change of distance with time (b) Concept of velocity as change of displacement with time (c) Uniform/non-uniform speed/velocity (d) Distance/displacement-time graph 9. Rectilinear acceleration (a) Concept of acceleration as change of velocity with time. (b) Uniform/non-uniform acceleration (c) Velocity-time graph, (d) Equations of motion with constant acceleration; Gravitational acceleration as a special case. (ii) show the difference between angular speed and velocity. (iii) show centripetal force. Banking of roads in reducing sideways friction should be qualitatively discussed. Metre per second (ms-1) as unit of speed/velocity. Ticker-timer or similar devices should be used to determine speed/velocity. Definition of velocity as ds/dt. Determination of instantaneous speed/velocity from distance/displacement-time graph and by calculation. Unit of acceleration as ms-2 Ticker timer or similar devices should be used to determine acceleration. Definition of acceleration as dv/dt. Determination of acceleration and displacement from velocity-time graph Use of equations to solve numerical problems.
