QUESTION 1: According to the text, what is the primary requirement for the science of movement?

QUESTION 2: According to the text, what happens if there is no well-established center of gravity?

The applied force remains constant
Rest inertia decreases
Much of the energy is wasted trying to lift the load rather than moving forward horizontally
Reduces the risk of joint collapse

Initiating the movement of a stationary object requires much more effort than keeping it in motion
Keeping an object rolling always requires more force than starting it
Inertia does not affect motor performance
Traction lines optimize inertia

Divides the body into anterior and posterior
Divides the structure into upper and lower hemispheres
Divides the structure into right and left halves and defines forward and backward movements
Corresponds to precise control of rotations around the longitudinal axis
