i think its momentum but I'm not sure.....
It takes no force to 'move' an object. There are trillions of objects that are moving right now with no forces acting on them. It only takes force to 'accelerate' an object ... to change its motion, by changing its speed or the direction of its motion. force=mass*acceleration As mass increases, so does the force needed to change the object's motion.
With changing the "state of motion", I assume you want to change the velocity. What you need here is a force, applied on the object. The amount of acceleration is given by Newton's Second Law.
Speed and direction of motion are needed to determine velocity.
That bend is needed in order to change rotational motion of the blades into the linear motion of moving air.

A Reference Point A reference point is needed to determine if an object is in motion.

force of compression
Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
Speed and direction of motion are needed to determine velocity.
Inertia is the tendency of an object to resist a change in its motion. Objects with more mass have more inertia. The more mass an object has the harder it is to change its motion. Thats is how inertia effects and object. (Don't worry I got this from my Science Textbook)
