The object has 1 J of P.E. What is the work done in terms of height?
Correct answer: A. 1 J
- A. 1 J
- B. 10 J
- C. 0 J
- D. 0.1 J
Explanation
The work done in terms of height to give an object 1 Joule (J) of potential energy is 1 J. So, the correct answer is: 1 J

About Potential Energy
Potential energy is energy stored because of position or configuration, including gravitational potential energy near Earth's surface and elastic energy in a stretched or compressed spring. Questions use changes in potential energy and conservation of mechanical energy, while distinguishing a chosen reference level from an absolute zero of energy.
