Whats the difference between kipping pull ups and ordinary pull ups?

Ive often heard that kipping is cheating with a pull up,thats because they are infact two completely different exercises, achieving two different objectives.so i depends what your training for

with an ordinary pull up, the idea is to pull yourself up isolating parts of the body to train the specific parts,like a pull down machine,your body in a stable position isolating certain muscle groups, like the back etc, pull ups are an exercise for strength

now with kipping pull ups they are designed to use the whole body in an explosive flowing movement,strengthening the kinetic chain as a whole,not just isolating certain muscles,this makes a kipping pull up an "explosive move for bodyweight training"

and like with any exercise push yourself to hard and you will injure yourself,ive trained pull ups but never kipping pull ups,I dont think my back could take the whip.
