Friction or gravity .
The surface of an object affects the aerodynamic drag: a force which acts against the direction of motion.
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
Friction acts in the opposite direction of the object's motion
Friction is a force that always acts in a direction opposite to that of motion. So the frictional force does negative work on the velocity of an object ( thus reducing the speed of an object).
"an object at rest will stay at rest, unless moved by a(n) outside force(net force). an object in motion will stay in motion, unless stopped by an outside force or friction.

Friction.
it usually does, but if the force is balanced, it will not change the object's motion
Friction .
An applied force will change the motion of an object. Such as a thrust, or an impact.
-- First of all, motion doesn't require any force.-- If the forces on an object are unbalanced, then the object's motion changes. Always.-- If the forces on an object are balanced, then the object's motion doesn't change.
yes
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
Friction.
friction is a contact force
because of the inertia of the object as stated by Newton's first law of motion.
