friction
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.
friction
Elastic collision: objects bound against each other after the collision. - One is moving and the other is at rest. - Both objects are moving. Inelastic collision: objects stick together after the collision. - One is moving and the other is at rest. - Both objects are moving.
An objects acceleration depends on its mass and the force acting on it. Newton's second law, F = ma.

Force is the only thing that causes the accelerationof material objects, whether they're moving or not.

Its slowing down (but still moving).

Acceleration due to gravity, -9.81 m/s^2, is just like any acceleration. As time continues, a moving objects speed increases.
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
