Forces in physics pdf
Webforce, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. The concept of force is commonly explained in terms of Isaac Newton’s three laws of motion set forth in his Principia Mathematica (1687). According to Newton’s first principle, a body that is at rest or moving at a uniform rate in a straight line will remain in that state … http://www.xtec.cat/sgfp/llicencies/200708/memories/1729/str_unit2.pdf
