Physical Dimensions, Units, and Observable QuantitiesPhysical Dimensions, Units, and Observable Quantities Summary: In this class, you will learn to differentiate fundamental quantities such as mass, length, and time, and how they relate to derived units like area and force. You will discover the importance of comparable observable quantities in the...
Reflection in Plane and Spherical Mirrors Abstract: In this class, we will review the basic principles of geometric optics, focusing on reflection in plane and spherical mirrors. It defines key terms such as light ray, point object, and point image. Additionally, it addresses the sign convention for mirrors and Descartes'...
Fundamentals of Kinematics: Position, Velocity, and Acceleration Summary: In this class, we will review the fundamental concepts of kinematics: position, velocity, and acceleration. We will explore how to represent position as a function of time, differentiating between instantaneous and average velocity and acceleration. Additionally, we will derive the equations of...
Domain, Range, and Graph - Proposed and Solved Summary: In this class, we practice how to determine the domain, range, and graph of algebraic functions through exercises and solved examples, highlighting the importance of practice to master these techniques. Learning Objectives: By the end of this class, the student will...
Methods of Electrification by Contact, Friction, and Induction In this class, we will review the three methods of electrification: contact, friction, and induction. The atomic structure of matter is introduced, differentiating between conductors and insulators. It describes how bodies gain or lose electric charge through these methods, highlighting that induction...
Plane Mirrors, Solved Problems Summary: In this class, we will review some solved problems of plane mirrors. The angle of reflection is determined based on the angle between two plane mirrors joined by a hinge, and specific examples are calculated. Critical values of are examined so that the ray bounces...
Solved Problems of Spherical Mirrors In previous classes, we already covered all the theory related to plane and spherical mirrors, and examples of reasoning with plane mirrors were also shown. Now it is time to review some solved problems with spherical mirrors. Below, we will review some typical problems about...
Coulomb's Law and the Electrostatic Force The "Coulomb's Law and the Electrostatic Force" has not only expanded our understanding of electric forces but also generated unexpected anecdotes. Benjamin Franklin, during an experiment to stun and cook a turkey with electricity, ended up as the test subject: a discharge left him...
Rectilinear Uniform Motion (R.U.M.) Summary: In this class, we will focus on applying the equations to rectilinear uniform motion, which is essential to understand how objects move at a constant speed. We will review the equations on the axis and see their simplification when the acceleration is zero, allowing us...
Uniformly Accelerated Rectilinear Motion (UARM) Summary: In this class, we will review the concept of uniformly accelerated rectilinear motion (UARM). We will explain how this type of motion implies constant acceleration in a straight line and is modeled through equations obtained by integration. Learning Objectives: By the end of this...
