What principle is the resistance to change in motion?

• force-motion

• force-time

• inertia

• range of motion

What is the ability to main control of joint/body position by resisting forces?

• balance

• stability

• mobility

• base of support

Which principle indicates the optimal timing of muscle activation and segment rotations is dependent on the movement goal?

• coordination continuum

• segmental interaction

• optimal projection

• spin

• preparation

• observation

• evaluation/diagnosis

• intervention
