Planetary Weight Calculation Worksheet

Solar system with planets orbiting the Sun

🌟 Part 1: Understanding Gravity

1. What keeps the planets in orbit around the Sun?

The Sun's magnetic field

The Sun's gravitational pull

Solar wind

Planetary rotation

2. Why does your weight change on different planets?

Your mass changes

Gravity is different on each planet

The atmosphere is different

The distance from Earth changes

3. The formula for calculating weight on other planets is:

Weight on planet = Earth weight ÷ gravity factor

Weight on planet = Earth weight × gravity factor

Weight on planet = gravity factor - Earth weight

Weight on planet = gravity factor + Earth weight

🧮 Part 2: Weight Calculations

Planetary Gravity Factors:

Mercury: 0.38 | Venus: 0.91 | Mars: 0.38 | Jupiter: 2.36 | Saturn: 0.92 | Uranus: 0.89 | Neptune: 1.13

4. My weight on Earth: _________ pounds
5. Calculate your weight on each planet. Show your work in the boxes below:

Mercury: _______ × 0.38 = _______ pounds

Venus: _______ × 0.91 = _______ pounds

Mars: _______ × 0.38 = _______ pounds

Jupiter: _______ × 2.36 = _______ pounds

6. On which planet would you weigh the most? _________________
7. On which planet would you weigh the least? _________________

🚀 Part 3: Critical Thinking

8. If you could jump 2 feet high on Earth, approximately how high could you jump on Mars? Explain your reasoning.
9. An astronaut weighs 180 pounds on Earth. How much would they weigh on Jupiter? Show your calculation.
10. Explain why understanding planetary gravity is important for space exploration.
Extension Challenge: Research and explain why Jupiter has such strong gravity compared to Mars, even though both are planets.
