Explanation:
This is a formula from elementary physics, where the (h) is the distance a projectile has fallen after time (t), assuming a starting velocity of zero. The constant (g) is acceleration due to gravity and has a value of 9.8 meters per second squared (9.8m/s^2).
Examples: If you drop a ball from a 500 meters cliff, in 10 seconds it would fall a distance, h = 1/2*9.8m/s^2*(10s)^2 = 490 meters .
