An object weighs less on Mars than on Earth because Mars has what?
- A lighter object
- Weaker gravity there
- Thicker air there
- Stronger gravity there
Show answer and solution
Correct answer: B. Weaker gravity there
1. Weight is the pull of gravity on an object.
2. Gravity is weaker on Mars, so the pull and the weight are less.
3. The mass of the object itself is unchanged.
