Question

Suppose you weigh 115 pounds . How much would you weigh on each of the other planets in our solar system? Assume you can stand either on the surface or in an airplane in the planet's atmosphere. (Hint: Recall from Chapter Light and Matter that weight is mass times the acceleration of gravity. The surface gravity column in the table below tells you how the acceleration of gravity on other planets compares to that on Earth.)

1. On Mercury

2. On Venus

3. On Mars

4. On Jupiter

5. On Saturn

6. On Uranus

7. On Neptune

8. On Pluto

Explanation / Answer

Mass is constant while weight differs from place to place and for different celestial bodies. Weight is the product of mass x acceleration due to gravity. The gravitational factor of different planets with relative to earth is given below:

Mercury: 0.38 i.e. weight is 115x0.38= 43.7 lbs

Venus: 0.91 i.e. weight in venus is 115x0.91= 104.65 lbs

Mars is 0.38 i.e. weight is 115x0.38= 43.7 lbs

Jupiter: 2.54 i.e. weight is 115x2.54= 292.1 lbs

Saturn: 1.08 i.e. weight is 115x1.08= 124.2 lbs

Uranus: 0.91 i.e weight is 115x0.91= 104.65 lbs

Neptune: 1.19 i.e. weight is 115x1.19= 136.85 lbs

Pluto: 0.06 i.e. weight is 115x0.06= 6.9 lbs.
