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 the same
- 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: Apply the equation Ep = m x g x h when gravitational field strength is given.. 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
Common Mistake in Gravitational Potential Energy Calculation
Students often confuse the variables in the equation Ep = m x g x h, mistakenly using height in kilograms instead of metres.
Always ensure that height (h) is measured in metres when applying the gravitational potential energy equation.
