Escape velocity, at the surface of the earth, is just about a whopping 11.2 km/s. This means that, to completely escape the force of earth's gravity, from the surface of the earth with the only outside for being gravity, you would need to be going this speed to escape (ignoring, of course, drag - drag forces at those speeds would rip a spaceship apart). So on my way to physics last friday I thought about how to reach those speeds, without the use of costly rocket fuel. One (although initially
Over the summer, I learned a lot about light, and I welcome the opportunity to share that with you. One thing I learned about was how different light sources stacked up against one another. Most people know that incandescent bulbs (tungsten-halogen, the "normal" kind) are less efficient that LED or fluorescent bulbs, but don't know why. I'm here to alleviate that knowledge gap.
The reason incandescent bulbs are inefficient is because they produce a lot of heat - not just their own heat, bu
Sometimes I like to sit back and pump some jams. Before the invention of all this modern technology such as speakers and cds and digital audio, such things just weren't possible. Music had to be performed. But with the invention of electrical speakers that all changing. People were able to finally jam out.
The common speaker relies on the principles of electromagnetism. In the center is a magnet (attached to a speaker cone), surrounded by a coil. As the current through the coil fluctuates, the
In the past few years, the Dyson Air Multiplier has revolutionized the field of recreational air transportation. It's for this reason that I feel it warrants a blog post, all to itself. Lauded for a lack of (visible) fan blades, it is safer than the more common axial-style fan.
The Man Behind the Magic
But how is this trickery pulled off? Allow me to explain.
The Dyson Air Multiplier does, in fact, have typical fan blades. But instead of being open to the air, they are hidden
I'm a new Physics AP-C student, and I would like to tell you a little bit about myself. I'm an avid programmer/science enthusiast, and am looking towards entering a scientific or science-related field. I (as one may assume) like science and math, and more leisurely things like playing video games or disc golfing. Things of the sort.
The reason I'm taking Physics AP-C this year is because I'm interested in learning more about physics and I want to solve more challenging problem
