These are what I covered this week:
S4 A. Math: We started on Differentiation – Idea of limits and the derivative, dy/dx, power rule. Students find it interesting that we can determine the gradient at a point on a curve without drawing a tangent.
S4 Physics: We started on Static Electricity – the idea of charge, the coulomb, insulators, conductors, charging by friction, charging by induction, charging by contact, earthing, electric fields, applications of electrostatics. Unfortunately textbooks, don’t cover much about what happens when a charged insulator touches another insulator, when an insulator touches a conductor (either is charged), and when a conductor touches another conductor (either or both initially charged).
S3 A.Math: We revised the beginnings of Logarithms a bit as a new student has just joined. Conversion of index form to log form and vice versa, base e and base 10.
S3 Physics: We revised Kinematics because of a new student – distance vs displacement, speed vs velocity, deceleration vs negative acceleration, scalars and vectors, kinematics formulae.
