In this video, we look at how particles move in gases and how this leads to gas pressure. We then explore how changing the temperature changes the kinetic energy of the gases and how this changes the pressure.

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.

#gravity #science #song
A song I wrote to introduce my elementary students to the concept of gravity and to 'maybe' explain why I'm always falling down! (lyrics below)
From Newton's basic laws of motion.
LYRICS
Gravity is all around,
When I fall it pulls me to the ground!
A force that you and I can’t see,
Pulls me toward you, and you towards me!
Keeps us from flying into space,
Why I fall when I trip on my shoelace,
That cool force is gravity,
Thank Isaac Newton’s apple tree!
Gravity,
A force that’s pulling you and me,
Gravity,
Pulls Jupiter, Mars, and Mercury,
Gravity,
A force that’s pulling you and me,
Down and down,
As our Earth spins round and round…
I fall,
You fall,
We all fall down!
The force of gravity
Pulling us to the ground,
You can never see it,
It never makes a sound,
It makes our mother Earth,
Go round, and round and round,
The planets have their orbits,
Because of gravity,
Pulls on flying objects,
Pulls on you and me!
Makes an apple fall,
Lets us slip down slides,
Makes a yo-yo go,
And oceans have their tides!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!
Hey gravity, hey gravity hey,
Don’t make me fall down today!
Here’s the reason, why I’m scared,
32 feet per second squared!
Hey gravity, hey gravity hey,
Don’t make me fall down today!
Here’s the reason, why I’m scared,
32 feet per second squared!
Gravity,
A force that’s pulling you and me,
Gravity,
Pulls Jupiter, Mars, and Mercury,
Gravity,
A force that’s pulling you and me,
Down and down,
As our Earth spins round and round…
Pulls Jupiter, Mars, and mercury,
And all the planets I can see,
Pulled in orbits around the sun,
The sun is pulling everyone?
Sun has so much gravity,
A whole bunch more than you and me!
Great big mass, big gravity,
I’d weigh much more on the sun you see…
I’d weigh much more,
On the sun you see,
Great big ball of mass,
Means more gravity,
The great amount of mass,
Means the greater the pull,
A dog has less mass,
Than a cow or a bull!
It’s not too strong,
But it’s all around,
If it was real strong,
We couldn’t jump up off the ground,
Gravity’s good,
Based on mass not girth,
Gravity’s good,
It holds us to the Earth!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!
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!

Director Christopher Nolan and author Kip Thorne speak to TIME's Jeffrey Kluger about the physics of 2014 blockbuster Interstellar. There's no arguing about the blockbuster status of Interstellar, director Chris Nolan's latest box office phenomenon. But plenty of people are debating the science component of that sci-fi tale'”which is how it always is when a movie based in something as non-negotiable as physics has to take just enough liberties to make the fiction part of the story fly. Nolan was determined to keep his narrative scientifically honest, which is why he signed on as technical adviser celebrated Caltech physicist Kip Thorne'”who literally wrote the book on (much of) the movie's cosmology. TIME's Jeffrey Kluger sat down with Nolan and Thorne to talk about human curiosity, the art of sci-fi filmmaking and the one time the two of them locked horns over a plot point.

This is the Map of Quantum Physics and quantum mechanics covering everything you need to know about this field in one image. Check out this video's sponsor https://brilliant.org/dos
And grab this poster here: https://store.dftba.com/collec....tions/domain-of-scie
I’ve been fascinated with quantum physics and quantum mechanics for a very long time and I wanted to share the subject with you so I made this map of quantum physics to lay out the ideas within the subject, to set some bounds on it so you know its not endless and to introduce you to lots of concepts that if you are interested in them you can dig deeper. When you are approaching a subject like this that’s so complicated it can be quite challenging because you don’t know where to start and you don’t know how all the concepts relate to each other so hopefully this will put everything in context.
This playlist expands on this video with lots of other more specific videos that dive deeper: https://www.youtube.com/playli....st?list=PLOYRlicwLG3

In this video, we look at refraction of waves. First we explore what is meant by refraction and look at how this is due to changes in the speed of waves as they change from one medium to another. Finally, we use the idea of wavefronts to explain how changes in wave speed cause refraction.

NOTE: We would like to correct an error in this video. Birds do not get electrocuted when resting on power lines because there is no path to ground. Electricity has to flow from a place of high potential to low potential to electrocute. If a bird were to touch the line and some grounded metal of some kind, they could be shocked.
Hello Teachers and Parents! In this video we will learn all about electricity. Your student(s) will learn about lightning, power plants, Direct Current (DC) and Alternating Current (AC). We even talk about when electricity was discovered and go over topics like conductors and insulators. By the time you are done watching this video your child will have a much better understanding of what electricity is, where it comes from, and the amazing things it can do.
We know that electricity can be a tricky topic to cover so throughout the video we provide really good examples and break down the complex ideas. We also have a complete lesson plan full of worksheets and activities that will help your student practice what they are learning. You can download for free here: https://learnbright.org/lesson....s/science/electricit
In this video we will learn:
0:00 What is Electricity?
1:38 What is a Direct Current?
4:13 What is an Alternating Current?
5:55 How do Power Plants produce Electricity?
6:51 How do Magnets create Electricity?
7:33 What is Static Electricity?
8:35 What is a Conductor?
9:08 What is an Insulator?
10:21 When was Electricity Discovered?
11:31 Learning Activity | Can you solve the Electricity Riddle?
