Force is the only thing that causes the acceleration
of material objects, whether they're moving or not.
In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
The force that decreases the acceleration of two objects moving against each other is the gravitational force.

The direction of average acceleration is downwards, in the direction of gravity. This is because gravity affects all objects, even objects that are moving in other directions.

concervation of momentum concervation of momentum 2nd Answer: Well, not really, no. Friction causes moving objects to slow.
Its slowing down (but still moving).
Gravity have you been paying attention in school!
I believe gravity would fit that description.
