For my senior year, the school sprang for a FORTRAN compiler to run on the business office NCR computer. My job was to run the students punch-card decks through the computer during the business office lunch hour. Spent an interim month learning to use FORTRAN as a language usage analysis tool, under tutelage of a Classic Languages professor.
electric forces can be attractive or repulsive, whereas gravitational forces are only attractive.
Electricity and magnetism are two aspects of electromagnetism. Electric forces are produced by electric charges either at rest or in motion. Magnetic forces, on the other hand, are produced only by moving charges and act solely on charges in motion. Electric and magnetic forces can be detected in regions called electric and magnetic fields.
