Final answer:
The statement regarding ruling a patient on their weak side is false in the context of physics and also in practical application. Two unequal forces result in movement in the direction of the net force, which is usually towards the greater force. However, with proper support, a patient's movement can be assisted on their weaker side.
Step-by-step explanation:
Addressing the question of force dynamics, it is False to claim that a patient can never be ruled on their weak side. In the context of physics, when two unequal forces act on a body, the resulting motion of the body will be in the direction of the net force, which is typically in the direction of the stronger force. This principle is based on Newton's second law of motion, which states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
In practical terms, if a patient is considered a body in the context of this question, and we consider 'rule' to mean move or control, it is still inaccurate to state that you can never rule a patient on their weak side. For instance, if a patient has a weaker arm due to injury, it is still possible to assist movement on that side with proper care, support, and by applying enough force in the desired direction to overcome the limitations of weakness.
