... 1/ The Earth rotates at a constant rate, with a period of 24 hours. What force (or torque) causes the rotation of the Earth? Explain. No force (or torque) causes the rotation of the Earth. The Earth continues to rotate because inertia (Newton’s first law of motion). [2 points] 2/ Throw a baseball st ...

... Two magnets (north and south) are placed a distance apart such that a magnetic field (B) exists from north to south. A circuit is set up so that current flows as shown above through the magnetic field. (note: the center piece (shown as a thick solid line) is called the rotor and is free to rotate ar ...
