I. Foucault's Pendulum. One is the Foucault experiment. This was first conducted in 1851, by the Frenchman Léon Foucault. He suspended a heavy iron ball from a 200 ft (61 m) wire, creating a pendulum, from the dome of the Pantheon in Paris. He put sand underneath the pendulum, and placed a pin on the bottom of the ball, so it would leave a mark on its swing from side to side. On each swing, over the course of 24 hours, the mark in the sand would move to the right. The direction in the path showed movement of the earth against the swing of the pendulum.
2)A more modern proof of the rotation is shown by the orbits of artificial satellites. A satellite is launched from the Kennedy Space Center at a 30 degree angle to an orbit 100 mi (161 km) above Earth. Its orbit stays at approximately the same plane in space. If Earth did not rotate, the satellite would pass over Cape Canaveral each time it completed an orbit, but it does not. As it completes the first orbit, it flies over Alabama and over Louisiana on the third. Each time the satellite passes over locations in the United States, it is 1,000 mi (1,609 km) farther to the west. Tracking stations have made this observation with hundreds of satellites.

See how easy it is to prove.
