Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

In this tutorial we begin to explore ideas of velocity and acceleration. We do exciting things like throw things off cliffs (far safer on paper than in real life) and see how high a ball will fly in the air.
Displacement, velocity, and time
Kinematic formulas and projectile motion
You understand velocity and acceleration well in one-dimension. Now we can explore scenarios that are even more fun. With a little bit of trigonometry (you might want to review your basic trig, especially what sin and cos are), we can think about whether a baseball can clear the "green monster" at Fenway Park.
Two-dimensional projectile motion
Optimal angle for a projectile
3. Forces and Newton's laws of motion
This is the meat of much of classical physics. We think about what a force is and how Newton changed the world's (and possibly your) view of how reality works.
Newton's laws of motion
Normal force and contact force
Balanced and unbalanced forces
Slow sock on Lubricon VI
Inclined planes and friction
4.Centripetal force and gravitation
Learn about centripetal acceleration and centripetal force. Also, learn about the universal law of gravitation and gravitational orbits.
Circular motion and centripetal acceleration
Newton's law of gravitation
5.Work and energy
"Energy" is a word that's used a lot. Here, you'll learn about how it's one of the most useful concepts in physics. Along the way, we'll talk about work, kinetic energy, potential energy, conservation of energy, and mechanical advantage.
Work and energy
Springs and Hooke's law
6.Impacts and linear momentum
Momentum ties velocity and mass into one quantity. It might not be obvious why this is useful, but momentum has this cool property where the total amount of it never changes. This is called the conservation of momentum, and we can use it to analyze collisions and other interactions. Bam!
Momentum and Impulse
Elastic and inelastic collisions
Center of mass
7.Moments, torque, and angular momentum
Everything you've learned about motion, forces, energy, and momentum can be reused to analyze rotating objects. There are some differences, though. Here, you'll learn about rotational motion, moments, torque, and angular momentum.
Torque, moments, and angular momentum
8.Oscillations, Mechanical waves, and sound
Waves are responsible for basically every form of communication we use. Whether you're talking out loud, texting on your phone, or waving to someone in a crowd there's going to be a wave transmitting information. Learn about the basics of waves in this topic, then learn more about light waves in the topics below.
Simple harmonic motion
Simple harmonic motion (with calculus)
Introduction to mechanical waves
The Doppler effect
Atmospheric pressure is like an invisible friend who is always squeezing you with a big hug. Learn more about pressure, buoyant force, and flowing fluid so you can appreciate the sometimes invisible, but crucial, effect they have on us and the world around us.
Density and Pressure
Buoyant Force and Archimedes' Principle
Heat can be useful, but it can also be annoying. Understanding heat and the flow of heat allows us to build heat sinks that prevent our computers from overheating, build better engines, and prevent freeway overpasses from cracking.
Temperature, kinetic theory, and the ideal gas law
Specific heat and heat transfer
Laws of thermodynamics
11.Electric charge, field, and electric potential
Electric forces hold together the atoms and molecules in your eyes which allow you to read this sentence. Take a moment and learn about the force that holds our bodies together.
Charge and electric force (Coulomb's law)
Electric potential energy, electric potential, and voltage
Circuits make computers, digital cameras, and video games possible. Circuits are driving an unprecedented rate of change in how we live. In this topic you'll learn about the physics behind the electronic devices we use.
Ohm's law and circuits with resistors
Circuits with capacitors
13.Magnetic forces, magnetic fields, and Faraday's law
Magnetic fields are extremely useful. The magnetic field of the Earth shields us from harmful radiation from the Sun, magnetic fields allow us to diagnose medical problems using an MRI, and magnetic fields are a key component in generating electrical power in most power plants. In this topic you'll learn about the forces, fields, and laws that makes these and so many other applications possible.
- Magnets and Magnetic Force
- Magnetic field created by a current
- Electric motors
- Magnetic flux and Faraday's law
14.Electromagnetic waves and interference
Light can seem mysterious. What is light made out of? What causes color? How do 3D movies work? Learn about some of the mysterious properties of light in these tutorials.
Introduction to electromagnetic waves
Interference of electromagnetic waves
Light waves can be bent and reflected to form new and sometimes altered images. Understanding how light rays can be manipulated allows us to create better contact lenses, fiber optic cables, and high powered telescopes.
Reflection and refraction
Think you know about time and space? Think again. Einstein basically did a pile driver on all our brains when he came up with his theory of special relativity.
Michelson and Morley's luminiferous ether experiment
Einstein velocity addition
Do you want to describe the microscopic world of atoms and nuclei? Well, classical physics isn't going to cut it. You'll need quantum physics to explain things like atomic energy levels, photons, and the wavelength of electrons.
