F = ma; Is acceleration possible without any motion?

Well, yes, the gavity is pulling you down, and you are not moving. So you are subjected to an acceleration and are not moving.
Mind you, one can argue that the *resulting* force is zero, as the ground is reacting with an equal and opposite force to your weight; if you take it that way, to have an unbalanced force should result in motion.

A force can exist without any motion -- your weight on your chair for example. Since acceleration is defined as the change in velocity of motion,it can't exist in a system with no motion.

Absolutely. Imagine an object sitting on your kitchen table. That object has (at least) two forces acting on it: the force of gravity acting downward, and the force of the table exactly balancing it out.
Acceleration depends on the NET force acting on an object, which is the result of unbalanced sets of forces -- as opposed to the balanced, static set of forces in my example.

gravity is a force with no motion.
F = Gm(1)m(2)/r^2 where G is the gravitational constant.

Would explain the Clinton adminstration, wouldn't it? No, not according to the laws of physics according to Newton's Second Law.

all motion is relative
