Question
- A. Mass is in kg, while weight is the gravitational force measured in N.
- B. Mass and weight are both forces.
- C. Weight is in kg and mass is in N.
- D. Mass changes when gravitational field strength changes.
Answer
The correct answer is: Mass is in kg, while weight is the gravitational force measured in N.
Explanation
The correct option is Mass is in kg, while weight is the gravitational force measured in N.. This fits Energy transfer and braking in Work done and energy transfer because it uses the named force or motion relationship in the situation, gives the correct unit or graph meaning where needed, and avoids the specific misconception in the distractors.
Common mistake
Misunderstanding Energy Dissipation
Students often think that increased speed only affects the distance required to stop, not the amount of energy that must be dissipated.
Emphasize that as speed increases, the kinetic energy of the vehicle increases, which means more energy must be dissipated by the brakes to bring the vehicle to a stop.
