Question
- A. It shows constant speed because the gradient is constant.
- B. It shows constant acceleration because all straight lines accelerate.
- C. It shows the object is stationary.
- D. It shows distance from the area under the line.
Answer
The correct answer is: It shows constant speed because the gradient is constant.
Explanation
The correct option is It shows constant speed because the gradient is constant.. 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
Understanding Constant Velocity
Students often think that an object must be accelerating if it is moving, failing to recognize that it can move at a constant velocity when the resultant force is zero.
Emphasize that constant velocity means no change in speed or direction, which occurs when all forces acting on the object are balanced, resulting in a zero resultant force.
