Two metal spheres of different masses are released from rest at the same height above the ground. Air resistance is negligible.
Which row in the table correctly describes what will happen and the physical reason for it?
| What will happen | Reason | |
|---|---|---|
| A | Both spheres hit the ground at the same time | The acceleration of free fall is independent of mass |
| B | Both spheres hit the ground at the same time | They both fall with a constant speed |
| C | The heavier sphere hits the ground first | The acceleration of free fall increases with mass |
| D | The heavier sphere hits the ground first | The gravitational force is greater on the heavier sphere |
