Question
- A. The mass of the object
- B. The acceleration
- C. The distance travelled
- D. The time taken
Answer
The mass of the object
Explanation
To accurately investigate the effect of force on acceleration, the mass of the object must be kept constant while varying the force applied.
Common mistake
Misunderstanding Graph Relationships
Students often plot graphs without correctly identifying the relationship between force, mass, and acceleration, leading to incorrect conclusions about how these variables interact.
To fix this, students should review Newton's second law (F = ma) and ensure they understand how to derive acceleration from force and mass when plotting their graphs. They should also practice identifying the correct axes and units for each variable.
