Mechanical engineers are often engaged in the creation, modification and maintenance of machines and mechanisms. Machines transform energy, or change the direction and rate of applied forces in order to produce useful amounts of work. The term Work refers to the application of force through a given distance. Expressed as a algebraic statement, Work = Force x Distance. Since this implies movement, it is clear that motion is an essential component of mechanical assemblies. This lesson serves as an introduction to basic concepts and the technical literacy associated with motion.
