Translational kinetic energy of a body is equal to one-half the product of its mass, m, and the square of its velocity, v, or 1/2mv2. For a rotating body the moment of inertia, I, corresponds to mass, and the angular velocity (omega), ω, corresponds to linear, or translational, velocity. Accordingly, rotational kinetic energy is equal to one-half the product of the moment of inertia and the square of the angular velocity, or 1/2Iω2. [pdf]

Wind Power Facts. Today more than 72,000 wind turbines across the country are generating clean, reliable power. Wind power capacity totals 151 GW, making it the fourth-largest source of electricity generation capacity in the country. This is enough wind power to serve the equivalent of 46 million American homes. [pdf]

Consider an electric field generated by a positive point charge. The direction of the electric field is such that it is radially outwards. When a positive test charge is brought closer to the point charge, it will experience repulsion due to electrostatic or Coulomb force. Energy is needed to overcome the repulsive force and move the test charge closer to the point charge, which is a source charge. This energy is known as electric potential energy. [pdf]

Alessandro Giuseppe Antonio Anastasio Volta was born on February 18, 1745, in Como, Lombardy (now in Italy). He became professor of physics at the Royal School of Como in 1774. In 1775 Volta's interest in electricity led him to improve a device used to generate static electricity. Volta discovered and isolated methane gas in 1776. Three years later he was appointed to the chair of physics at the University of Pavia (now in Italy). [pdf]
