Matter can neither be created nor destroyed...but potential energy can be converted into a different kind of energy. Let's say we have a spring with a mass connected to it. This mass is a magnet, and the apparatus is inside a copper coil. It's a horizontal magnet with friction minimized at the...
The medium plays a very big role in wave speed. If the waves travel along a string, the lower the mass and greater the density of the string, the faster waves travel across the string. Waves also travel much more slowly in the air than they do underwater or along a dense string. I'm sure the...
I understand the concepts behind the terms in the title; however, I have a question about how to transform the wave energy itself. I'm working on a science fair project that involves transforming sound energy into electrical energy--I understand this is not a very reasonable method of harvesting...
