Question
Two objects, a hammer and feather in vacuum falling freely near the surface of the moon would:
- Have same velocities at any instant
- Have different accelerations
- Experience forces of the same magnitude
- Undergo a change in their inertia
Hint:
Free fall is independent of mass.
The correct answer is: Have same velocities at any instant
The correct option is a) Have same velocities at any instant.
If an object is in free fall, its acceleration depends only on gravitational acceleration, not mass. Because of this, an object in free fall always has the same velocity, regardless of its mass.
