Question

A. The area under a velocity-time graph represents distance travelled.
B. The area represents resultant force.
C. The area represents acceleration only.
D. The area is used on distance-time graphs to find distance.

Answer

The correct answer is: The area under a velocity-time graph represents distance travelled.

Explanation

The correct option is The area under a velocity-time graph represents distance travelled.. This fits Resultant forces in Forces and their interactions 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

Misinterpreting Free-Body Diagrams

Students often confuse the direction of force arrows in free-body diagrams, leading to incorrect interpretations of the forces acting on an object.

To fix this, students should carefully analyze the problem, ensuring they understand the direction of each force and accurately represent it with arrows in their diagrams.
