Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. It increases.
- B. It decreases.
- C. It remains constant.
- D. It becomes kinetic energy.
Answer
It decreases.
Explanation
The correct option is "It decreases.". It decreases. is right because it directly matches Changes in energy: Identify gravitational potential energy in joules, mass in kilograms, gravitational field strength in newtons per kilogram and height in metres.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Confusing Units of Measurement
Students often confuse the units for gravitational potential energy, mass, and height, mixing up joules, kilograms, and meters.
Always remember that gravitational potential energy is measured in joules (J), mass in kilograms (kg), and height in meters (m). Double-check your units when performing calculations.
