Maybe you want to learn physics. Perhaps you don’t know anything about it, but you want to learn more. Either way, this article is for you. If you wish to learn physics and succeed in doing homework, you will find this guide to be very different. It is for those who want to delve deeper into problems in physics.

Topics associated with physics homework:

  1. Mathematical Preliminaries

We’ll start with the basic math, but there’s no need to go down the rabbit hole if you already understand calculus. We’ll be using various time units and units of distance. We express every measurement made in our lives in these units. Every quantity that can be measured or sensed is at some point defined about these units.

  1. Introduction to Mechanics

Mechanics is the study of forces and motion. To understand why this subject lies at the core of physics, you must understand that all matter in the universe interacts based on its properties and the properties of nearby matter. It includes gravity and electromagnetism.

  1. Electrostatics

Electrons in atoms are held in place by the electrical attraction between their electrons and protons. To understand this, we’ll express electric charge in terms of protons and electrons. We’ll then consider the rest of the universe and find that they repel each other when we bring two positive charges together. The electricity produced is equal to the force between them, which is different from their electrical attraction.

  1. Waves and Vibrations

Waves are a mechanism for transmitting energy without mass. They are also helpful in transmitting energy through space at the speed of light. To fully understand them, you must understand their source and their effects. The source is the electricity that moves through the circuit or pushes and pulls on an object. We can see the effects in transmission lines and antennas.

  1. Modern Physics

The first three topics are classical physics. We’ll see that quantum mechanics, which deals with the behavior of sub-atomic particles, differs from classical mechanics. We’ll also see how relativity deals with massless objects that approach the speed of light.

  1. Classical Mechanics

We’ll start with Newton’s laws of motion. The first two describe an object’s changes in velocity while forces are acting upon it. The third law states that for every action, there is an equal and opposite reaction. We’ll then interpret these ideas for objects that are not moving or are moving at constant speeds.

  1. Electrodynamics

Electrons, protons, and neutrons are the building blocks of atoms. They form a part of many chemical reactions and create light when they vibrate. We’ll then see that the forces that hold the particles together are not electrical but rather magnetic. The magnetic field is stronger at the center of a current-carrying wire than at its ends.

  1. Quantum Mechanics

We can bring sub-atomic particles like electrons, protons, and neutrons as wave-like or particle-like (waves). We do not know much about these particles, but many predictions that they make are both precise and tested. We’ll see that much of modern physics deals with the nature of sub-atomic particles.

  1. Thermodynamics and Statistical Mechanics

The fourth law of thermodynamics states that energy cannot be created or destroyed by a system. It can only be converted to another form and then converted back to its original state. These ideas become very important when considering the amount of energy in a system and extracting it.


This series is a roadmap that will lead you through the fundamentals of physics. Each post has a curriculum associated with it which you can use to follow along. There is no need to keep up with it as I’ll provide many alternatives for those who want them.
