Question
- A. In the seat belt scenario, apply resultant force to explain that a non-zero resultant force can change an object's motion while keeping resultant force versus balanced forces separate.
- B. In the seat belt 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 explain that a non-zero resultant force can change an object's motion.
Answer
The correct answer is: In the seat belt scenario, apply resultant force to explain that a non-zero resultant force can change an object's motion while keeping resultant force versus balanced forces separate.
Explanation
The correct option is In the seat belt scenario, apply resultant force to explain that a non-zero resultant force can change an object's motion while keeping resultant force versus balanced forces separate.. It is correct because the scenario says a passenger is brought to rest over a longer stopping time, which must be interpreted through Resultant forces. This directly supports the learning objective to explain that a non-zero resultant force can change an object's motion. Use values 4, 8, and 16 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
Misunderstanding Resultant Forces
Students often think that a non-zero resultant force only affects the speed of an object, ignoring changes in direction.
Emphasize that a non-zero resultant force can cause both a change in speed and a change in direction of an object's motion.
