Motion 03:44
If I was drifting in outer space No gravity keeping me in place Well I could move at a constant pace I’d be in motion But if I was acted on by a force It could change my speed and alter my course And I would do the same to them in reverse I’d be in motion We are in motion Standing on a planet that’s in motion Moving round a star that’s in motion Part of a galaxy in motion We are in motion And if you’re moving to the left Or moving to the right If you’re sleeping in your bed Or if you’re dancing all night We are in motion Part of a Universe in motion If you knew my trajectory And you could measure my velocity Well you could calculate where I’ll be Motion is change in position over time If I’m going fast, my velocity is high, but If it looks like I am standing still to your eye A body in motion will tend to stay in motion A body at rest will tend to stay at rest Force is equal to the mass of a body Multiplied by the acceleration of the body When a body exerts a force on another body The other body exerts the same force in the opposite direction

We know all matter’s made of atoms but what holds them together? What binds the molecules in objects and makes them feel solid? And what gives everything around us all the different colours Let’s go on a journey of electromagnetic knowledge! Think about this fact: Particles with the same charge will repel and with the opposite charge they'll attract Electromagnetism Electromagnetism Electromagnetism Seems like magic but it’s science Positive and negative attraction It’s a fundamental interaction Studying the universe in action Using science Just like the sun’s gravity keeping the planets in motion Inside an atom the protons pull the electrons in the shell But unlike gravity, which only ever pulls things together Particles with the opposite charge will attract but with the same charge they will repel When atoms get excited, they start to send out Electromagnetic vibrations We call it light or gamma rays or maybe radio waves Based on the frequency of oscillation

Particle 03:26
One day I started shrinking to a microscopic size And all the objects that had seemed so solid to my eyes Looked different at this level and just then I realized That it’s all made up of particles It’s all made up of particles I saw molecules just like the kind that make up me and you And they were made of atoms doing things that atoms do And they were made of protons, neutrons, and electrons too It’s all made up of particles Down to the molecules Down to the atoms, the elements Down to the protons and electrons Everything’s made of particles Down to the quarks and the bosons At the quantum level Everything’s made of particles I approached the quantum level and I still was shrinking fast Saw the quarks that make up matter and the bosons with no mass I wondered if I’d keep on shrinking or this level was the last If it’s all made up of particles I found it most peculiar that these phenomena behave In some ways like a particle, in others like a wave And maybe on some level they are really just the same If everything is particles and everything is waves Then I returned to normal size and pondered where I’d been How rocks and trees the air we breathe and even you and me Are all made up of building blocks too tiny to be seen

Wave 05:38
Why don’t we wave our arms in front of us together, like they’re floating on the water Let’s bring them down and to the left, and up and to the right, then back the other way If you calculate the distance between the furthest left and furthest right What you’re measuring is the wavelength of the wave Pretend the water’s getting choppier, and your arms are bobbing further down and further up Let’s bring them way way down and bring them way way up, and then we do the same If you calculate the distance between the highest and the lowest points What you’re measuring is the amplitude of the wave Everything is waves Everything is waves Everything is waves Everything is waves And waves Go up and down And side to side They’re all around The sound we hear The light we see Matter and energy You know that everything is waves Why don’t we make our waves go a little faster now Let’s bring them down, and up, and down, and up, then back the other way If you calculate how many waves you do for every bar of this song What you’re measuring is the frequency of the wave I found it most peculiar these phenomena behave In some ways like a particle, in others like a wave And maybe on some level they are really just the same If everything is particles and everything is waves

Matter 04:06
When you are brand new your eyes are wide Each day you’re growing, your cells divide Metabolizing the energy You’re made of matter and you matter to me I’ll try to teach you what you need to know Give you the care that you need to grow You’re growing every day, it’s fascinating to see You’re made of matter and you matter to me Sometimes you might be sad or lonely Somedays you laugh and some days you cry But even in the hardest moments It’s wonderful that you’re alive And when the sun shines you run and play Or in the night time after a busy day You are a marvel of biology You’re made of matter and you matter to me I’ll give you food you may not always like I’ll give you guidance, I may not always be right I’ll give you love times infinity You’re made of matter and you matter to me As you get older, you continue to change Each day the world seems a little less strange I hope you’re always fascinated by the mystery You’re made of matter and you matter to me Sometimes you might be sad or lonely Somedays you laugh and some days you cry But even in the hardest moments It’s wonderful that you're alive And when the sun shines you run and play Or in the night time after a busy day You are a marvel of chemistry You’re made of matter and you matter to me But even in the hardest moments It’s wonderful to be alive And if the sun shines you run and play Or in the night time after a busy day I hope you’re always fascinated by the mystery Cuz it’s a marvel just to be a human being You’re made of matter and you matter to me
