Physics of Stopping a Bike

In short, braking is a tool for converting kinetic energy into heat (http://en.wikipedia.org/wiki/Brakes). This is done by applying friction in some way. In the case of a disc brake, friction occurs because the brake mechanism exerts a force on the fracture pad to bring them into contact with the disc. This combination with the fact that the disk rotates and this kinetic energy is converted to heat. If the purpose of the brakes is to convert kinetic energy to heat, we need to investigate how much kinetic energy is in the mobile bike to see how much heat the brakes generate.

In this article, someone in Switzerland asked a question. "It is easy to ride a bicycle when moving, why did it stop?" - AS, Switzerland. The answer comes from the physicist Lou A. Bloomfield at the University of Virginia balancing the palm broom (air broom head) with balance, gravity, and the physics behind the forward movement. In articles that do not deal with mathematical expressions, the reader can understand how gravity, balance, and forward movement can keep the bicycle steady and can help with weighting and manipulating the bicycle. With this information, I think I can stay on their broom with Magic, Harry Potter and other Quidditch players. As you have noticed in the movie, everyone is not riding a broom. Returning to Miss Gulch, she and her bicycle became evil witches. Like her bicycle, Gulch / Witch handles her magic and physics very well.

For many years I've been riding, I have never heard that this bicycle is called a broom. People who know me riding a bicycle remind me of the famous Almira (I always thought that it was Elvira) Gulch / Wicked Witch's theme came from "Oz Wizard" . This song seems to be targeted especially for middle-aged women riding a bicycle. But I sometimes hear it in my mind. We can not escape. But it's called a broom back to the bicycle. Of course, when I put a pointer to the Velenari Weatherwax pulldown handle on my Surfly Long Haul Trucker, I imagine that I would tilt and turn like the best Quidditch player in Harry Potter's story can do. Sliding along a big hill or mountain can of course be felt like flying. I passed through Manhattan, experienced various transit traffic, and I can feel magical in my own way.
