• ## Motion in a Straight Line | Crash Course Physics

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.

• ## Derivatives | Crash Course Physics

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.

• ## Integrals | Crash Course Physics

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!

• ## Vectors and 2D Motion | Crash Course Physics

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?

• ## Newton's Laws | Crash Course Physics

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.

• ## Friction | Crash Course Physics

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! Today, Shini tells us about Static and Kinetic friction; how they work and how they're different.

• ## Uniform Circular Motion | Crash Course Physics

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.

• ## Newtonian Gravity | Crash Course Physics

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.

• ## Work, Energy, and Power | Crash Course Physics

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!

• ## Collisions | Crash Course Physics

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.

• ## Rotational Motion | Crash Course Physics

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!

• ## Torque | Crash Course Physics

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."

• ## Statics | Crash Course Physics

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!

• ## Fluids at Rest | Crash Course Physics

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.

• ## Fluids in Motion | Crash Course Physics

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?

• ## Simple Harmonic Motion | Crash Course Physics

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.

• ## Traveling Waves | Crash Course Physics

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!

• ## Sound | Crash Course Physics

We learn a lot about our surroundings thanks to sound. But...what is it exactly? 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.
