In a vacuum (no air):
-Both boxes fall at the same rate and hit the ground at the same time.
-Gravity accelerates all objects equally at 9.8 m/s², regardless of mass.
In real-world conditions (with air):
-Air resistance affects lighter or less compact objects more.
-A box full of feathers may fall more slowly if it’s larger or less aerodynamic.
-A box full of bricks is denser and experiences less drag → more likely to hit the ground first.
If both boxes are the same shape and size:
-Air resistance affects them similarly.
-They will fall at nearly the same rate and land around the same time.
