Force: A push or pull on an object.
true
Momentum is not considered a force because it is a vector quantity that describes an object's motion, while force is a vector quantity that describes the interaction between objects that causes a change in motion. Momentum does not directly cause motion to change, rather it reflects the amount of motion an object has.
Interaction between objects that causes a change in motion.
An external force is a force that causes a change in an object's motion by pushing or pulling it in a certain direction. This force can accelerate, decelerate, or change the direction of the object's movement.
The term is inertia. It is the property of matter that causes objects to resist changes in their state of motion.
I think this question is not phrased very well. Any force can change objects velocity (speed+direction). If fact that is the definition of the force - F=ma any force, by definition itself, can change objects velocity. Maybe you meant what force can change objects direction of motion? In that case - any force that has a different direction (not the same as direction of motion) Any force can change an object's motion.
Balanced forces that net to zero cause no change in an object motion.

Velocity is a change in an object's motion OR direction of motion.
The change in an objects position is called motion.
FRiction
Forces can change the motion of objects by causing them to speed up, slow down, change direction, or deform. This change in motion is governed by Newton's laws of motion, which describe how forces interact with objects to cause them to accelerate or decelerate.
