You should already know that velocity-time graphs look like this... and how we can use them to map out a journey. If you’re unsure, you may want to watch this video first...In this video we’re going to look at the area under these graphs and what they represent. Let’s start by looking at a simple v
Pi is the ratio of a circle’s circumference to its diameter. And it doesn’t matter how big or small the circle is, the ratio always stays the same: pi. That’s why pi is called a constant. Authors: ZDF/Terra X/Bilderfest/Lena Paul/Dirk Hagen/Saba Bussmann/Jochen Schmidt Translation and dubbing: alu
Equations are used everywhere: in computers, business, internet searches, medicine to name a few examples. Which is why we study them a lot in Maths. We have names to describe the different parts: coefficients, variables, constants and exponents. A variable is a symbol for a number we don’t know y
Learn the basics about the law of constant composition and how to apply it. JOIN our platform at www.fuseschool.org This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind FuseSchool. These videos can be used in a flipped c

There are two leading ways to measure the universe's rate of expansion, and for fifteen years, they more or less agreed with one another. Not anymore, and that’s a big deal. Visit http://science.nasa.gov/ for more. Click here to see more videos: https://alugha.com/NASA
The law of mass action is applied to the autoprotolysis of water. Through further considerations, a constant Kw can be defined. This is called the ionic product of water. This is the basis of the pH value. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done

Astronomer Doris Daou explains how the forces of speed and gravity keep the Moon in a constant orbit around Earth in this animated video segment adapted from NASA. The Moon, Earth's natural satellite, seems to hover in the sky, unaffected by gravity. However, the reason the Moon stays in orbit is pr
In algebra we have lots of different names for different things: expressions, equations, formulae and identities are all slightly different versions of similar things. Then within these, we have variables, constants, coefficients and exponents to describe the different parts. We also need to know wh
The reaction speed of the enzyme-catalyzed reactions depends on various factors. In this screencast, the dependence on the substrate concept is explained and the curve is derived. Finally, the Michaelis constant is described. Original: "Wolfgang Dukorn" Original: German. All translations in this v
Homeostasis is a term first defined by Claude Bernard in 1865. It means maintaining a constant internal environment. This is a bit like how our brain works. Sensors all around the body are measuring various things and sending the information back to the brain the brain in does its best to keep all t
