If gravity became stronger, would lifting the same box to the same height require more work?

If gravity became stronger, would lifting the same box to the same height require more work?

• A. Yes
• B. No
• C. Depends on other factors
• D. Not enough information

Answer: (A)

Lifting a box to a fixed height requires work equal to the gravitational force you must overcome times the distance moved: W = m g h. For a given box (mass m) and height (h), if gravity (g) becomes stronger, the force you need to apply increases, so the work increases in direct proportion to g. Therefore more work is required to lift the box to the same height when gravity is stronger. This matches the choice that says yes. The other options don’t fit because, with mass and height fixed, changing gravity changes the required work; there’s no need to invoke other factors or claim insufficient information in this ideal scenario.
