It seems that we humans are always jumping through hoops. Did you know that elephants are the only land mammal that can’t jump. Jumping, or leaping, is a form of locomotion or movement in which a living or non-living (e.g., robotic) mechanical system propels itself through the air under their own momentum and the force of gravity in a particular trajectory. Some animals, such as the kangaroo, employ jumping (commonly called hopping) 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. One way to classify jumping is by the manner of foot transfer. There are five basic ‘jump classifications’:
- Jump — jumping from and landing on two feet
- Hop — jumping from one foot and landing on the same foot
- Leap — jumping from one foot and landing on the other foot
- Assemble — jumping from one foot and landing on two feet
- Sissonne — jumping from two feet and landing on one foot
Aren’t you glad we don’t have leaping elephants!?
