In a vacuum, a stone and feather fall at the same time. Can you make the assumption that the acceleration of gravity acting on both objects is the same? Explain.

Answer 1

If there are no other forces, then the acceleration is the same, but the force depends on their mass.

a=F1/m1=F2/M2

so the quantity (F/m) does not imply force is the same unless mass is the same.
