The sign for "jump" depends on your
meaning and who or what is doing the jumping. A needle on a meter jumping
is signed much differently than a human being jumping. A "cow
jumping over the moon" is signed much differently than a little bird hopping
around.
The generic sign for jump is to use an upside down "V" to represent what it
looks like when a person jumps:

JUMP (generic):
Notes:
Don't use the generic two-legged "JUMP" sign (above) for concepts other than standard human or primate jumping or leaping. If you want to sign "My heart jumped" then use a flutter motion near your heart. If you want to sign "Dad helped me jump my car (battery)," Then do a mime type motion (instrument classifier) showing the attaching of the jumper cables (the thumb, index, and middle fingers latch on to imaginary battery posts).
Suppose you were talking about a horse riding competition and needed to indicate
that the horse jumped over something. You would use a two handed version of the
the sign "jump."
