Physics is associated with the study of matter and energy and the relationship between the two. In college, many students find physics as a hard subject full of complex laws, theories and formulas. However, physics is an easy and fun subject when well understood. Although many may argue that physics use weird formulas to explain a phenomenon, the topics are quite impressive. Here are the best 20 interesting physics topics that every physics student should strive to understand. Believe me or not, when you do your best to grasp the concepts behind these topics will add a little magic to your peers. Great topics, great concepts, great physicist!
Electrostatics
This is a branch of physics that deals with the study of electric charges at rest. This topic teaches us more about the Coulomb's law, conductors, electric fields, electric dipole movement, Gauss law, insulators, polarization density and triboelectricity.
Kinematics
This is a branch of classical mechanics that studies the motion of objects, bodies and points without further consideration of the forces that cause such motions. This topic will cover more on celestials, continuum and analytical dynamics. In physics, the word energy refers to a quantitative property transferred to an object for it to perform or work. Here, you will learn more about the law of conservation of energy, different types of energy and how mass and energy are related.
Forces and Newton's laws
This topic explains in details more on a meaning and different types of forces. It also tackles in details the concept of the three fundamentals Newton's laws of motion.
Circular motion
This topic will teach more about circular motion and the forces associated with it such as centripetal force. It will also talk more about the equations applicable in determining the motion as well as more of velocity, relativistic circular motion and acceleration
Waves and sound
This topic covers more about waves as well as sound as a part of the waves. It teaches about different waves, characteristics of waves and properties of waves such as period and amplitudes. It will also tackle different types of sound waves and their properties.
Thermodynamics
Thermodynamics is associated with temperature and heat. This topic covers more about the movements of heat energy such as conduction, convection and radiation. It will also expound on branches of thermodynamics such as classical thermodynamics, statistical mechanics, chemical thermodynamics and equilibrium thermodynamics.
Electromagnetism
This is a cool topic that covers electromagnetic forces and the laws that govern these forces. Laws that will be discussed in details in this topic are Lenz's law, Faraday's law and Lorentz force law.
Atomic theory
The topic covers more on the nature of atoms and the components that constituents an atom. It will also expand on Avogadro constant, isotopes, Brownian motion and quantum physical models of the atom.
Special relativity
This topic explains more about special relativity theory, principles of relativity, Lorentz transformation, consequences that are derived from the Lorentz transformation, optical effects and its relationship with the theory of quantum mechanics
Radioactivity
The topic covers in details on the types of radioactivity particles such as gamma, beta and alpha. It also expounds on radio decay and the theoretical basis of decaying phenomena such as the half-life.
Fluids
A fluid is a substance that continuously flows under certain shear stress. This topic will cover fluid concepts such as smart fluid, Ferrofluid, non-Newtonian fluids, fluid dynamics as well as fluid mechanics.
Electric circuits
This topic explains more about the types of electric circuits such as analog circuits, digital circuits and mixed-signal circuits.
Gravity
This topic covers Newton's theory of gravitation and its relationship with other fields of study such as astronomy. It also covers anomalies and discrepancies of gravity.
Oscillations
The topic digs deep into the meaning of oscillation and its types such as neural oscillation, self-oscillation and pilot induced oscillation.
Nuclear physics
This topic explains more about modern nuclear physics and its concepts such as nuclear decay, nuclear fission and nuclear fusion.
Impulse and momentum
This topic covers more on different types of momentum, and it's relation with other theories such as quantum field theory, a theory of relativity and electrodynamics.
Refraction
This topic explains how light waves behave when passing from one media to another.
Reflection
The topic covers concepts of reflection of light such as reflection nebula and reflection seismology.
Vectors
This topic tries to cover some concepts of physics such as vector field, vector space and Euclidean vector.
