The term force is c. 1300, "physical strength," from Old French force "force, strength; courage, fortitude; violence, power, compulsion" (12c.), from Vulgar Latin *fortia (source also of Old Spanish forzo, Spanish fuerza, Italian forza), noun use of neuter plural of Latin fortis "strong, mighty; firm, steadfast; brave, bold."

Number, quality, switching barriers, customer loyalty, uniqueness, substitution, cost of change, differences, size, price sensitivity, specialist knowledge, economies of scale, technology protection, and barriers to entry. May the forth be with you.
