What is the difference between Parkour and Freerunning? Are flips parkour?

Parkour explores the idea of efficiency, speed, power and functionality, from Point A to B. There is also an emphasis on usefulness and readiness in its philosophy! Freerunning is understood to be more about play, self-expression, creativity and engaging your environment. Along those lines, flips generally can be understood to be an expression of freerunning but not parkour. However, many practitioners of movement do both! We would like to express that names at any point, especially at an introductory level, are no matter of concern. What is important is that you MOVE and enjoy every single bit of it!
