This equation calculates the vertical distance traveled by an object in free fall starting from rest, assuming constant gravitational acceleration and no air resistance.
Use it when an object is dropped without initial velocity and gravity is the only significant force acting on it.
If an object falls for 3 s on Earth:
h = 0.5 × 9.81 × 3² = 44.145 m
