Suppose you weigh 105 . How much would you weigh on 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.)
Use your table, or one like it, to obtain the factor you will use to multiply by 105 pounds. There are plenty of such tables on the internet.
The weight will be the same whether on the surface or in an airplane in the same planet's atmosphere.

To calculate your weight on other planets in our solar system, we need to use the equation: weight = mass * acceleration due to gravity.
Here's how you can calculate your weight on other planets:
1. Determine your mass: Mass is a measure of the amount of matter in your body and remains constant regardless of the planet or location. Let's assume your mass is 105 kg (kilograms).
2. Look up the acceleration due to gravity on each planet: The acceleration due to gravity on different planets varies based on their size and mass. You can find this information in the table below:
Planet | Surface Gravity (g)
-------------------------------
Mercury | 0.38
Venus | 0.91
Earth | 1.00
Mars | 0.38
Jupiter | 2.34
Saturn | 1.06
Uranus | 0.92
Neptune | 1.19
3. Calculate your weight on each planet: Multiply your mass by the respective acceleration due to gravity for each planet to find your weight. The formula will be: weight = mass * acceleration due to gravity.
Here are the calculations for each planet:
- Weight on Mercury: weight = 105 kg * 0.38 = 39.9 kg
- Weight on Venus: weight = 105 kg * 0.91 = 95.6 kg
- Weight on Mars: weight = 105 kg * 0.38 = 39.9 kg
- Weight on Jupiter: weight = 105 kg * 2.34 = 245.7 kg
- Weight on Saturn: weight = 105 kg * 1.06 = 111.3 kg
- Weight on Uranus: weight = 105 kg * 0.92 = 96.6 kg
- Weight on Neptune: weight = 105 kg * 1.19 = 124.9 kg
So, your weight on other planets in the solar system would vary depending on the respective acceleration due to gravity on each planet.
