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.
In physics, a force is an interaction between two objects that has the ability to change the motion of one or both of the objects. One of the fundamental forces of the universe is the electric force. This is the force that exists between all charged particles. The electric force is responsible for such diverse phenomena as making your hair stand up on a cold, dry day, creating chemical bonds, and allowing you to see when you turn on a lamp on a dark night.
