Jumping or leaping is a form of locomotion or movement in which an organism or non-living (e.g., robotic) mechanical system propels itself through the air along a ballistic trajectory. Jumping can be distinguished from running, galloping, and other gaits where the entire body is temporarily airborne by the relatively long duration of the aerial phase and high angle of initial launch.
Some animals, such as the kangaroo, employ jumping (commonly called hopping in this instance) as their primary form of locomotion, while others, such as frogs, use it only as a means to escape predators. Jumping is also a key feature of various activities and sports, including the long jump, high jump, and show jumping.

Famous quotes containing the word jumping:
“Everything seems beautiful because you don’t understand. Those flying fish, they’re not leaping for joy, they’re jumping in terror. Bigger fish want to eat them. That luminous water, it takes its gleam from millions of tiny dead bodies, the glitter of putrescence. There’s no beauty here, only death and decay.”
—Curtis Siodmak (1902–1988)
“We set up a certain aim, and put ourselves of our own will into the power of a certain current. Once having done that, we find ourselves committed to usages and customs which we had not before fully known, but from which we cannot depart without giving up the end which we have chosen. But we have no right, therefore, to claim that we are under the yoke of necessity. We might as well say that the man whom we see struggling vainly in the current of Niagara could not have helped jumping in.”
—Anna C. Brackett (1836–1911)
“Unwind, hands,
you angel webs,
unwind like the coil of a jumping jack,
cup together and let yourselves fill up with sun
and applaud, world,
applaud.”
—Anne Sexton (1928–1974)
