To make an object start moving is called acceleration, and it is done by exerting force on that object.
The force required to start an object moving is called static friction. It is the force that acts between two objects in contact that are not yet moving relative to each other. It must be overcome to initiate motion.
An object keeps moving once an applied force causes it to start moving because of inertia, which is the tendency of an object to resist changes in its motion.
An object at rest cannot start moving with no forces.
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.
An external force is needed to start an object moving. This can be applied through pushing, pulling, or some other method that imparts kinetic energy to the object.

The force that puts an object into motion is called a "push" or a "propulsive force." This force is responsible for overcoming inertia and causing the object to start moving.
The force that sets an object in motion is called the initial force or the applied force. This force overcomes the object's inertia and causes it to start moving.
Gravity
the speed of an object in a particular direction
Inertia
The best, purest answer is: Because no force at all is required to keep a moving object moving.
I have to guess either gravity or friction.If by that you mean a force that opposes the start of motion, then your force would be static friction.Static friction only occurs before an object starts moving, as opposed to kinetic friction which occurs when the objects is moving or sliding. The equation for static friction is: Ff = (coefficient of static friction) * FNInertia
