The author has examined the 80s since the published version of the 1983 edition of the high school textbooks (A) the first volume of uniform linear motion is defined as moving objects in a straight line, if at equal time speed Equal change, the object’s motion is called uniform speed linear motion, or simply referred to as uniform speed motion. 1991 edition of high school textbooks (compulsory) first volume of uniform variable linear motion is defined as: objects in a straight line movement, if equal Time
