The frictional force needed to start an object at rest into motion is the static frictional force. This force must be overcome by an external force before the object can start moving. Once the object is in motion, the kinetic frictional force will oppose its movement.
No, according to Newton's first law of motion, an object at rest will remain at rest unless acted upon by an external force. Without a force acting on the object, it will not start moving.
An external force, such as a push or a pull, can start a moving object by overcoming its inertia and setting it in motion. Once the object is in motion, it will continue moving until acted upon by another force.
The rate at which an object is moving at a given instant is called its instantaneous velocity. It is the object's speed and direction at that specific moment in time.
The force needed to stop a moving object is equal to the object's mass multiplied by its acceleration. This force is generated by applying a force in the opposite direction to the object's motion, causing it to decelerate until it comes to a complete stop.
The best, purest answer is: Because no force at all is required to keep a moving object moving.
The frictional force needed to start an object at rest into motion is the static frictional force. This force must be overcome by an external force before the object can start moving. Once the object is in motion, the kinetic frictional force will oppose its movement.

Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.

The rate at which an object is moving at a given instant is called its instantaneous velocity. It is the object's speed and direction at that specific moment in time.
The force needed to stop a moving object is equal to the object's mass multiplied by its acceleration. This force is generated by applying a force in the opposite direction to the object's motion, causing it to decelerate until it comes to a complete stop.
Once an object is in motion, it already has momentum which helps maintain its speed. When an object is at rest, it requires more force to overcome inertia and set it in motion. This is why less force is needed to keep an object moving compared to starting it in motion.
