Exam-style question
Try this first
An object with a mass of 12 kg is raised from the ground to a height of 15 m. What is the change in gravitational potential energy? Scenario focus: potential gradients in a distinct A-Level Physics fields context; identify the field quantity, source, direction, and unit before selecting the answer.
Model answer
What a good answer should say
- The change in gravitational potential energy is 1764 J.
Explanation
Why this works
The correct answer is The change in gravitational potential energy is 1764 J.. This is correct for Gravitational fields because the stem is testing potential gradients; the chosen option keeps the field quantity, source interaction, direction, and unit consistent.
The alternatives are weaker because they mix gravitational, electric, magnetic, orbital, or transformer ideas, or they attach the right number to the wrong physical meaning.
