speed problem

The faster it is, the farther it reaches. By the other hand, if something is slow, doesn´t travel that much in the same amount of time. My question is, how to travel small distances with a fast speed? Obviously with a smooth and slow deceleration, so it feels natural.
Is it possible to do it at half way?
Thanks for everything!

umm. lets say you want to move your object 10 meters forward in 0.5 second (small distance with fast velocity)
i am thinking using Slerp ( for natural acceleration and deceleration) and RigidBody.addForce with forcemode VelocityChange

something like this :

        if(Vector3.Magnitude(V) <25)
        V = Vector3.Slerp(Vector3.zero,new Vector3(20,0,0),.25f);
        else V = Vector3.Slerp(new Vector3(20,0,0),Vector3.zero,.25f);
        gameObject.GetComponent<Rigidbody>().AddForce(V,ForceMode.VelocityChange);

Why else and why has to be less tan 25?
