Remember that feeling in your stomach when you were a kid, plummeting down the first drop of a rollercoaster? That's gravity doing its thing, and it's the same force that gives downhill cyclists their rush. But as the National Geographic show Science of Stupid hilariously demonstrates, gravity can be a cruel mistress if you don't respect the laws of physics.
Let's break down why downhill cycling, and even rollercoasters, are so exhilarating, and how understanding the science behind the thrills can keep you safe.
It's All About the Energy Transfer
Picture this: you're climbing a steep hill on your bike. Your legs are burning, you're sweating, but you're gaining something crucial – potential energy. This is the energy of position, stored up and ready to be unleashed.
Now, point your bike downhill. As you descend, that potential energy transforms into kinetic energy, the energy of motion. The steeper the hill, the faster you go, and the greater your kinetic energy becomes. This is why downhill speeds can be so exhilarating, and why it's crucial to understand the forces at play.
“The electric light, the telephone, the microchip. All great inventions. But for me, the most important of all was the wheel, mainly because it led to things like this. Downhill cycling.
