<p>This resource is for teachers of IGCSE physics, and students intending to write P51 or P52 IGCSE physics practical . It includes guides for writing plan or design for an experiment, illustrative examples drawn from past IGCSE past papers with write-up for the experimental design or plan, and questions for practice.</p>
This monograph contains important key points to be taken into consideration when taking measurements and reporting experiments most especially in physics and chemistry.<br />
Key notes considered as guiding rules for reporting experiment in IGCSE, AQA and GCSE physics and chemistry practical or tests of practical are outlined under the following - Table of observation/result, accuracy, graphs, slope of a graph, calculations from observational or experimental data, general precautions for practical in current electricity, light/optics, heat and mechanics as in physics.<br />
To buttress the importance of these rules, under the said headings, past questions were presented with the mark schemes and comments were presented in relation to the mark schemes. It is also useful to mention that this monograph is also very useful for AS physics students.
This activity-based teaching and learning resource and worksheet provides the students with opportunity to undergo real-time acquisition and application of knowledge and understanding as it is questioning learning biased and also provides the teacher with the opportunity to have student-centered lesson delivery useful for grade 11 and review in electromagnetic induction for AS students
This resource considered further examples on quadratic expressions, their factorization and the solutions of the associated quadratic equations by the method referred to as "determinant" method by the author.
<p>This paper is divided into five sections; Kinematics, Dynamics, Statics, Gravitation, and Work and kinetic energy. We presented the summary notes, exemplar questions and solutions, and self-test questions with answers. In our presentation of solutions to exemplar questions, it was not taken for granted that the paper is for College, Tertiary Institution, or University students and so explanations were offered for understanding. Analogies were applied where feasible. In dynamics for instance, without any rigorous mathematics, we establish the equations associated with the motion of a rocket; simply by considering Newton’s second law of motion using calculus and conservation of momentum principle in the absence of external forces as a starter, and by making an analogy to the rolling of a car tyre, the movement of a point on the tyre when escaping contact with the ground, the static friction and hence the traction or tractive force between the tyre and the ground and the direction of motion of the car, we justify the state of existence of each of the terms in the equation; and by extension, gravity was considered. The self-test and the exemplar questions are modeled after real-life situations. In our dealings with gravitation, we establish the gravitational potential at a point in the gravitational field by using the concept of work of gravity as the scalar product of the acting gravitational force vector and the displacement vector, all in the opposite direction to the unit vector in the outward radial direction.</p>
