A force of 1 newton accelerates a MASS of 1 kilogram to a speed of 1 meter per second in 1 second. Examples are coal, oil and natural gas. It takes millions of years to form fossil fuels. As the water passes through the runner and over the curved surfaces, it causes rotation of the runner. The rotational motion is transmitted by a shaft to the generator.
Water enters the turbine radially and leaves axially.
Oxygen in the atmosphere, which can be extracted at no cost. Conversely, oxygen extracted at a cost would cause the substance from which the oxygen molecules were taken to decompose. A type of lens built up from a number of narrow concentric segments. Surface resistance to relative motion, which slows down movement and causes heat. FUEL CELL .
