Final answer:
The statement pertains to Newton's third law of motion in Physics, which states that every action has an equal and opposite reaction, illustrating how two opposing forces are involved in interactions like batting a baseball or the operation of rockets.
Step-by-step explanation:
The statement 'These two opposing forces need to be somewhat balanced so that one doesn't overwhelm the other too' refers to Newton's third law of motion, which posits that forces always come in pairs of equal and opposite magnitudes. When a force is applied to an object, the object exerts an equal force in the opposite direction on the source of that force. Examples encompass everyday phenomena such as batting a baseball, the recoil of a rifle, or the operation of jet engines and rockets, where exhaust gases push backward, propelling the rocket forward.
It is important to note that these forces act on different systems, a concept that is critical when defining the 'system of interest' in physics problems. In mathematical terms, when analyzing forces, they can have opposite signs and the net force is determined by subtracting the smaller force from the larger force, taking into consideration the chosen coordinate system. Overall, understanding Newton's third law is essential for analyzing the origin of forces and determining which are external to a system.
