General Physics II (PHYS102) - Syllabus Overview

Course Description

This course is a continuation of General Physics I, focusing on topics in waves, thermodynamics, electricity, and magnetism. It is designed for engineering students and covers both theoretical concepts and practical laboratory applications. The course aims to develop a deep understanding of physical principles and their applications in engineering contexts.

Course Objectives

Key Concepts and Definitions

Oscillatory Motion and Simple Harmonic Motion (SHM)

• Oscillatory Motion: Repetitive back-and-forth movement about an equilibrium position.

• Simple Harmonic Motion (SHM): A type of periodic motion where the restoring force is proportional to the displacement and acts in the direction opposite to that of displacement.

• Equation of SHM: $x(t) = A \cos(\omega t + \phi)$ where $A$ is amplitude, $\omega$ is angular frequency, and $\phi$ is phase constant.

• Energy in SHM: The total mechanical energy is conserved and given by: $E = \frac{1}{2} m \omega^2 A^2$

Waves and Sound

• Wave: A disturbance that transfers energy from one place to another without transferring matter.

• Types of Waves: Longitudinal (e.g., sound) and Transverse (e.g., light).

• Wave Equation: $v = f \lambda$ where $v$ is wave speed, $f$ is frequency, and $\lambda$ is wavelength.

• Doppler Effect: The change in frequency or wavelength of a wave in relation to an observer moving relative to the source.

Thermal Physics and Thermodynamics

• Temperature: A measure of the average kinetic energy of the particles in a substance.

• Heat: Energy transferred between objects due to a temperature difference.

• First Law of Thermodynamics: $\Delta U = Q - W$ where $\Delta U$ is the change in internal energy, $Q$ is heat added to the system, and $W$ is work done by the system.

• Second Law of Thermodynamics: Entropy of an isolated system never decreases; heat cannot spontaneously flow from a colder to a hotter body.

Electricity: Charges, Fields, and Circuits

• Electric Charge: A fundamental property of matter that causes it to experience a force in an electric field.

• Coulomb's Law: $F = k_e \frac{|q_1 q_2|}{r^2}$ where $F$ is the force between charges, $q_1$ and $q_2$ are the charges, $r$ is the separation, and $k_e$ is Coulomb's constant.

• Electric Field: The region around a charged object where other charges experience a force. $\vec{E} = \frac{F}{q}$

• Gauss's Law: $\oint \vec{E} \cdot d\vec{A} = \frac{Q_{enc}}{\varepsilon_0}$

• Electric Potential: The work done per unit charge in bringing a charge from infinity to a point in space. $V = \frac{U}{q}$

• Capacitance: The ability of a system to store electric charge. $C = \frac{Q}{V}$

• Ohm's Law: $V = IR$ where $V$ is voltage, $I$ is current, and $R$ is resistance.

• Kirchhoff's Laws: Rules for analyzing complex circuits (junction and loop rules).

Magnetism and Electromagnetic Induction

• Magnetic Field: A region where a magnetic force can be detected, produced by moving charges or magnetic materials.

• Force on a Moving Charge: $\vec{F} = q\vec{v} \times \vec{B}$

• Electromagnetic Induction (Faraday's Law): $\mathcal{E} = -\frac{d\Phi_B}{dt}$ where $\mathcal{E}$ is the induced emf and $\Phi_B$ is the magnetic flux.
