Now we know that motion is a relative term.So absolute motion has no meaning, right? So aren’t Galileo’s view that earth moves around sun and the church’s old belief that sun moves around earth actually not equally correct or equally wrong? this is a question from hc verma’s concept of physics part 1.(from short answer…… Continue reading Relative Nature of Motion
