A unit of momentum. One Jehf is equal to one kg x m/s.
The unit name was created by two seniors at Houston County High School in Warner Robins, GA when they became tired of writing out and saying "one kilogram times meters per second." The notation for Jehf is a capital J with one line going across the top and a line below it on the right side, and it is a combination of a J and an F.
Q: If a 50kg object moves at 14 m/s, what is its momentum?
A: 700 Jehfs
