Question
- A. In the fluid depth scenario, apply resultant force to state that unbalanced forces have a non-zero resultant force while keeping resultant force versus balanced forces separate.
- B. In the fluid depth scenario, mix up resultant force versus balanced forces and ignore resultant force.
- C. Use a general revision statement without applying Resultant forces to the situation.
- D. Choose a different forces topic instead of explaining state that unbalanced forces have a non-zero resultant force.
Answer
The correct answer is: In the fluid depth scenario, apply resultant force to state that unbalanced forces have a non-zero resultant force while keeping resultant force versus balanced forces separate.
Explanation
The correct option is In the fluid depth scenario, apply resultant force to state that unbalanced forces have a non-zero resultant force while keeping resultant force versus balanced forces separate.. It is correct because the scenario says liquid pressure increases with depth below the surface, which must be interpreted through Resultant forces. This directly supports the learning objective to state that unbalanced forces have a non-zero resultant force. Use values 2, 6, and 14 only if the question asks for a calculation. The answer earns credit by naming the relevant force or motion quantity, using units when needed, and avoiding the boundary error resultant force versus balanced forces.
Common mistake
Confusing Balanced and Unbalanced Forces
Students often think that unbalanced forces mean that there is no movement, confusing it with balanced forces.
Remember that unbalanced forces result in a change in motion, while balanced forces mean the object remains at rest or moves at a constant velocity.
