Question
- A. The object's acceleration must be constant — definition focus for uniform acceleration
- B. This confuses velocity and acceleration and does not answer Uniform acceleration (HT only).
- C. This is too vague because it does not use the force or motion quantity named in the objective.
- D. This reverses the physical cause and effect for Forces and motion.
Answer
The correct answer is: The object's acceleration must be constant — definition focus for uniform acceleration
Explanation
The correct option is The object's acceleration must be constant — definition focus for uniform acceleration. The object's acceleration must be constant — definition focus for uniform acceleration is correct because it matches the approved learning objective to (HT only) Identify when uniform acceleration is required before using the equation. This answer belongs to Uniform acceleration (HT only) within Forces and motion, so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse velocity and acceleration, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misunderstanding Uniform Acceleration
Students often fail to recognize that uniform acceleration is only applicable in specific scenarios, leading to incorrect application of the equation.
To fix this, students should practice identifying scenarios where uniform acceleration occurs, such as objects moving in a straight line with constant acceleration, before applying the equation.
