The key variable that different the two type of jumps is direction of motion.
High Jump
A high jump involves vertical upward upward motion that is limited by gravity.
The maximum height reached during a high jump is given as;
H = vt - ¹/₂gt²
Long Jump
A long jump involves horizontal distance that is not affected by gravity.
The horizontal distance traveled during a long jump is given as;
H = vt
Thus, the key variable that different the two type of jumps is direction of motion.
