Jumping is a form of movement in which an organism propels themselves into an airborne state along a ballistic trajectory. Though one might run or walk leading up to a jump, a jump is characterized by the longer duration of the aerial phase and a higher angle of initial launch. Some species rely on jumping as a primary form of movement, such as the kangaroo, frog, or rabbit. Different classifications of jumps exist and are determined by the manner of foot transfer. For example, a traditional jump is defined as beginning and ending the movement on both feet, whereas a leap begins on one foot and ends on the opposite foot. Beginning and ending the movement on the same, single foot is considered a hop.
