PhysicsBack to Subjects
If you have ever imagined being a scientist, technologist, engineer or mathematician, you need to develop necessary competency in physical principals that govern our world. The physics is one of the fundamental subjects that you need master to create a successful and rewarding career in STEM areas. These topics will cover explanation and application of principles of physics applied in mechanics and kinematics of solids, fluids flows, thermal energy, electricity, magnetism, optics and modern physics related nuclear energy.
These topic will also prepare you for concepts related to advance placement (AP) physics B and C and concepts that are covered in the first course in college physics.
In electrostatics, you will learn about charges, electric filed lines and drift velocity of electrons, Gauss' law of electrostatic field, voltage difference and microscopic Ohm's law connecting voltage and current through the conductors. You will learn how some materials are conductors, some are semi-conductors and some are insulators of electrical charge.
The motion of electrical charge in an electrical filed gives rise to electrical potential which popularly measured in Volts. You will learn all about creation of potential difference in an electric field. And,how you can store electrical energy between two charged plates which is termed as capacitor. You will also learn charging and discharging of capacitors and how to connect capacitors in series and parallel to achieve necessary capacitance.
The motion of charges through a conductor gives rise to electrical current measured in Ampere. The current can flow through electrical circuits that are formed by connecting a battery with resistance using conducting wires. Electrical circuits follow the macroscopic Ohms laws which connects Current I Voltage V and resistance R to flow of current through the electrical circuits, V = IR. You will also understand and apply Kirchhoff's voltage laws of electrical loops, current law of nodes to analyze complicated electrical circuits. You will analyze circuits with series and parallel resisters and capacitors and combination of the two.
The force applied for on an object for a small duration causes change velocity of an object is studied under impact and impulse response. The change in velocity of an object is momentum. You will learn about impulse and momentum that leads to elastic and inelastic collisions.
Sir Isaac Newton's was 16the century British scientist who formalized laws of motion. The three laws postulated by Newton are the basis for the kinematics – motion of objects subjects to force. In this segment you will understand the laws of motion and how to apply these laws to determine position, velocity and acceleration of particles and rigid bodies.
The gravity affects everything on Earth and motion of planatary objects. Newton's Universal law of gravitation is basis for understanding gravitational acceleration of Earth and the motion of planetary objects and satellites. You will be able to calculate orbital motion of satellites, escape velocity of space craft to cross the gravitational field of Earth and understand Keplar's laws of planetary motion.
The thermal physics is all about heat and thermodynamics. You will learn about measuring temperature, transfer of heat, and conversion of heat energy into work. You will understand kinetic theory of gases, thermodynamic processes and heat engine cycles responsible for the generation of automotive power. You will understand the fours fundamental laws of thermodynamics.
In this topic you will learn about motion of mechanical waves caused by the longitudinal and transverse motion. You will know how the sound waves are created. Relationship between wavelength, frequency and wave numbers. You will also understand the standing waves in musical instruments and Doppler's effect for measuring speed of moving sound sources and Mach number to cross the sound barrier.
