Answer: Galileo Galilei and Isaac Newton. When a body performs uniform motion, it travels equal distances in equal intervals of time. hence, the object is moving with constant speed and zero acceleration. Since, on a circular path the direction of the object is changing continuously to keep it on the path, the motion of the object is called accelerated motion. Thank You very much..
