A)

The force in the two systems will be in opposite directions.
B)

The force is identical in the two systems.
C)

The force in the second system will be with less than the force in the first system.
D)

There is no relationship between the force in the two systems.
E)

The force in the second system will be with greater than the force in the first system.

In the absence of air resistance, a boulder and a pebble dropped from rest will fall with equal

1) forces of gravity. 2) accelerations. 3) energies. 4) all these. The reason that this quantity is not greater for the boulder than the pebble is that 5) both the boulder and the pebble fall at the same speed. 6) the initial potential energies of each is the same. 7) gravitational force acting on each is the same. 8) the greater gravitational force on the boulder acts on a correspondingly greater mass.
