What is negligence under Kentucky law?

What is negligence under Kentucky law for which someone can be legally liable is a question that will vary depending on the circumstances. But here is a general and elegantly stated definition of negligence under Kentucky law:

"Negligence, as used in law, may be defined as the failure to discharge a legal duty, whereby injury occurs. There can be no negligence where there is no duty imposed." Franklin v. Tracy, 117 Ky. 267, 77 S.W. 1113, 1115 (1904).
