### Course Overview

#### Course Synopsis

Classical Mechanics, which deals with the motion of bodies under the action of forces. This is often called Newtonian mechanics as well. Electromagnetism, whose objective is to study how charges behave under the influence of electric and magnetic fields as well as understand how charges can create these fields. Thermal Physics, in which one studies the nature of heat and the changes that the addition of heat brings about in matter. Quantum Mechanics, which primarily deals with the physics of small objects such as atoms, nuclei, quarks, etc. However, Quantum Mechanics will be treated only briefly for lack of time.

#### Course Learning Outcomes

At the end of the course, you should be able to:

• Describe the System International (SI) system of units. Describe the concepts of mass, length and time. Describe the concept of frames of reference.
• Use basic trigonometry in physics calculations. State the definitions of displacement, velocity and acceleration. State and use the equations of kinematics for motion with constant acceleration.
• Describe the nature of free-fall motion, both linear and in two dimensions.
• State the definitions and properties of vectors and scalars. Decompose a vector into its components and to reassemble vector components into a magnitude and a direction.
• State the definitions of work, kinetic energy and potential energy. To Begin developing a concept of energy- what is it, how it is transformed and transfer.
• Recognize and use the state variables-temperature, pressure, volume, moles that characterize macroscopic phenomena.
• Understand energy conservation as expressed in the first law of thermodynamics. Understand the thermodynamics of the four processes of an ideal gas.Convert temperature measurement from one scale to another. Solve basic problems on temperature, heat and thermodynamics.
• Visualize motion and develop intuition about waves and to become familiar with the properties of sinusoidal waves, such as wavelength, wave number, and frequency. Understand and use the principle of superposition and to understand that standing waves are the superposition of two traveling waves. Understand the basic properties of standing waves.
• Distinguish between electric force and electric field. Use coulomb law to calculate electric force between charges. Calculate the properties of electric dipoles.
• Implement Gauss’s law on electric flux through a closed surface to the charge enclosed by the surface. Use ammeter, voltmeter ohmmeter or potentiometer in a circuit. Analyze circuits that consist of both capacitor and a resistor.
• Analyze the motion of charge particles in a magnetic field and to differentiate between magnetic lines and electric lines. Understand ho interference helps to measure the extremely small distances. Interpret the nature of light using photo electric effect and Compton’s effect etc.
• Understand the concept given by De Broglie that tiny particles like electron proton behave like waves. Analyze the quantum mechanical behavior of a particle in a potential well. Understand the properties of atomic nuclei like, radii, spins and magnetic moment etc.Understand fission and fusion reactions that are happening in side the Sun.
