S1 E1 • Motion in a Straight Line
In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also, how does a physicist discuss speed as opposed to a police officer? And did you deserve that ticket? You can figure it all out with the help of Physics!

S1 E2 • Derivatives
CALCULUS! Today we take our first steps into the language of Physics; mathematics. Every branch of science has its own way to describe the things that it investigates. And, with Physics, that's math. In this episode, Shini talks us through derivatives and how calculus helps us to understand the world around us.
Première diffusion : 7 avril 2016
S1 E3 • Integrals
Continuing with last week's introduction of calculus, Shini leads us through the ways that integrals can help us figure out things like distance when we have several other key bits of information. Say, for instance, you wanted to know how far your window was off the ground. By using integrals, a tennis ball, and a stop watch, you can figure that out! It's all here in this episode of Crash Course Physics!
Première diffusion : 14 avril 2016
S1 E4 • Vectors and 2D Motion
Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of Vectors and Scalars so we can better understand how to figure out motion in 2 Dimensions. But what does that have to do with baseball? Or two baseballs?
Première diffusion : 21 avril 2016
S1 E5 • Newton's Laws
I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.
Première diffusion : 28 avril 2016
S1 E6 • Friction
Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it started moving? You might think it's all about weight, but actually it's about friction. Two kinds of friction! In today's episode of Crash Course Physics, Shini Somara tells us about Static and Kinetic friction; how they work and how they're different.
Première diffusion : 5 mai 2016
S1 E7 • Uniform Circular Motion
Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to discuss centripetal force, centrifugal force, and a few other bits of physics to help us understand Uniform Circular motion.
Première diffusion : 12 mai 2016
S1 E8 • Newtonian Gravity
I'm sure you've all heard about Isaac Newton and that apple that fell on his head and how that was a huge deal to our understanding of gravity. Well... let's talk about that. In this episode of Crash Course Physics, Shini sits down to talk about the realities of the apple story and how Newtonian Gravity is more than a little important.
Première diffusion : 19 mai 2016
S1 E9 • Work, Energy, and Power
When you hear the word, "Work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics and today, Shini is going to walk us through it. Also, Energy and Power!
Première diffusion : 26 mai 2016
S1 E10 • Collisions
COLLISIONS! A big part of physics is understanding collisions and how they're not all the same. Mass, momentum, and many other things dictate how collisions can be unique. In this episode of Crash Course Physics, Shini sits down to lead us through an understanding of collisions. Plus, she brings a long our old friend Sir Isaac Newton.
Première diffusion : 2 juin 2016
S1 E11 • Rotational Motion
Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Shini delves into the world of Rotational Motion!
Première diffusion : 9 juin 2016
S1 E12 • Torque
What is torque? This is one of those things that you may have heard about in passing but never really understood. In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and what it all has to do with this thing called "Moment of Inertia."
Première diffusion : 16 juin 2016
S1 E13 • Statics
The Physics we're talking about today has saved your life! Whenever you walk across a bridge or lean on a building, Statics are at work. Statics is the study of objects when they're NOT accelerating. In this episode of Crash Course Physics, Shini talks to us about stretching, compressing, and springing as they relate to Statics! Also... Game of Thrones.
Première diffusion : 23 juin 2016
S1 E14 • Fluids at Rest
In this episode of Crash Course Physics, Shini is very excited to start talking about Fluids. You see, she's a Fluid Dynamicist and Mechanical Engineer, so fluids are really important to her. Actually they're really important to anyone studying physics. So, let's start down this path of understanding, not only how fluids work, but what they are!
Première diffusion : 8 juillet 2016
S1 E15 • Fluids in Motion
Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a nice day? I'll give you a hint on that last one... it's lawn mowers. In this episode of Crash Course Physics, Shini talks to us about how Fluids in Motion are really, really, REALLY powerful things.
Première diffusion : 14 juillet 2016
S1 E16 • Simple Harmonic Motion
Bridges... bridges, bridges, bridges. We talk a lot about bridges in Physics. Why? Because there is A LOT of practical physics that can be learned from the planning and construction of them. In this episode of Crash Course Physics, Shini talks to us about a particular mistake made in engineering the Millennium Bridge which allows us to talk about simple harmonic motion.
Première diffusion : 21 juillet 2016
S1 E17 • Traveling Waves
Waves are cool. The more we learn about waves, the more we learn about a lot of things in physics. Everything from earthquakes to music! Ropes can tell us a lot about how traveling waves work so, in this episode of Crash Course Physics, Shini uses ropes (and animated ropes) to talk about how waves carry energy and how different kinds of waves transmit energy differently.
Première diffusion : 28 juillet 2016
S1 E18 • Sound
We learn a lot about our surroundings thanks to sound. But... what is it exactly? Sound, that is. What is sound? And how does it travel? And what is this Doppler Effect that we've heard so much about? In this episode of Crash Course Physics, Shini goes over some of the basics (and some of the not so basics) of the Physics of Sound.
Première diffusion : 4 août 2016
S1 E19 • The Physics of Music
Music plays a big part in many of our lives. Whether you just like to listen or you enjoy playing an instrument, music is powerful. So what is music? How does it work? What are the physics of music? In this episode of Crash Course Physics, Shini talks to us about how music functions in terms of waves and how these waves interact with our ears.
Première diffusion : 11 août 2016
S1 E20 • Temperature
Bridges. Bridges don't deal well with temperature changes. In order to combat this, engineers have come up with some work arounds that allow bridges to flex as they expand or contract. In this episode of Crash Course Physics, Shini talks to us about temperature and the ideal gas law. Also, we figure out how much air is in your car.

S1 E31 • Capacitors and Kirchhoff
By now you know your way around a basic DC circuit. You’ve learned how to simplify circuits with resistors connected in series and parallel with a single battery source. But a lot of the real-world circuits that you encounter — and will have to describe — are much more complicated. For example, what happens when there are MULTIPLE batteries, connected in ‘parallel’? And what happens when we add ‘capacitors’ into the mix, with resistors in our DC circuits? On this, our last go-round inside a DC circuit, we’ll encounter junctions, loops, and capacitors!
