### Common MCQ in Physics for Engineering | Part 1

Hello there, I just want to share the common Multiple Choice Questions (MCQ) in the subject Physics for Engineering. By the way, this is based as well on our Midterm Period. There are 30 questions here, you can use your search tool or Ctrl+F to locate it easily.

DISCLAIMER: This is based on our online midterm exam, I got a perfect score so I think this is all correct but, little errors are still possible. Credits will still apply to the book (University Physics 13th Edition by Young and Freedman), to my professor, and to the question maker.

D. Gravitational

24. Mechanical energy is conserved provided that  ____ work is done by nonconservative forces.
A. Either positive or negative
B. No positive
