Question
- A. In the book on table scenario, apply balanced forces to state that balanced forces have a resultant force of zero while keeping resultant force versus balanced forces separate.
- B. In the book on table scenario, mix up resultant force versus balanced forces and ignore balanced forces.
- C. Use a general revision statement without applying Resultant forces to the situation.
- D. Choose a different forces topic instead of explaining state that balanced forces have a resultant force of zero.
Answer
The correct answer is: In the book on table scenario, apply balanced forces to state that balanced forces have a resultant force of zero while keeping resultant force versus balanced forces separate.
Explanation
The correct option is In the book on table scenario, apply balanced forces to state that balanced forces have a resultant force of zero while keeping resultant force versus balanced forces separate.. It is correct because the scenario says weight and normal contact force act on one object, which must be interpreted through Resultant forces. This directly supports the learning objective to state that balanced forces have a resultant force of zero. Use values 7, 15, and 12 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 Forces
Students often think that balanced forces mean no forces are acting on an object.
Explain that balanced forces mean the forces acting on an object are equal in size and opposite in direction, resulting in a net force of zero.
