Numbering Code Year/Term U-LAS12 10026 LE57 2021 ・ Second semester 2 Lecture Mainly 1st year students For all majors English Tue.3 OKEYO, Kennedy Omondi (Institute for Frontier Life and Medical Sciences Senior Lecturer) The lecture will focus on enabling students, especially from non-physics majors, to grasp basic concepts and principles of physics, and to learn how to apply them to understand the physical world around us. Particular focus will be on problem solving in mechanics, which will be presented systematically so that students gain a deeper understanding of mathematical and logical treatment of familialr physical problems. To further cement understanding and nurture students' love for science, focus will be on interactive learning using newly developed online tools. 1) To introduce students with little physics background to basic but important concepts in physics. 2) To nurture students' problem solving ability in physics. 3) To impact a deeper understanding of familiar physical phenomena. The following topics will be introduced from the basics, assuming that students completely do not have or have little prior knowledge of physics. 1) Introduction to vectors in motion (2 weeks) Here we will learn about vectors and how to use them to describe motion in terms of position, displacement, velocity and acceleration. 2) Introduction to motion of objects in two dimensions (3 weeks) By the end of this topic, you will learn how to use vectors to describe both linear, projectile and circular motions, and also be able to derive the kinematic equations of motion when given displacement, velocity and a constant acceleration. 3) Introduction to Newton's laws of motion and momentum (2 weeks) We will learn about Newton's laws of physics which form the foundation of modern physics. We will explore the relationship between force and acceleration, and extend the Newton's laws to momentum and conservation of momentum. Practical application to solving common motion problems in nature will be presented. 4) Introduction to work and energy (2 weeks) Work and energy are important physical properties. We will learn about how work is done when a force moves from one point to another. We will derive the relationship between work and energy (work-energy theorem). Concepts of potential energy and kinetic energy and the law of conservation of mechanical energy will be introduced. 5) Introduction to simple circular motions and oscillations (3 weeks) Sometimes motion occurs in a circular path, like when you drive around a curved road. This topic will introduce you to forces involved in circular motion such as centripetal forces. We will make everything pretty simple so that by the end of this topic, you will be able to derive the basic equations of circular motion. We will also look at harmonic oscillation exhibited by a mass attached to spring, i.e., Hooke's law. 6) Introduction to electricity and magnetism (2 weeks) A simplified introduction will be given to highlight the basics of both electricity and magnetism. 7) Exam and feedback (2 weeks) 1) Weekly assignments will be given to gauge students' understanding of the lecture contents. 2) Evaluation Assignments: 40% End-term exam: 60% None Students are encouraged to spare enough time for revision and review of previous lectures and read ahead in preparation for future lectures.
