Challenge Problems
Push your limits with challenges.
Question 1
An astronaut has a mass of 70 kg on Earth. Calculate their weight on Earth, then on the Moon where g = 1.6 m/s². How does this illustrate the difference between weight and mass?
💡 Hint: Use the formula W = mg for both calculations.
Question 2
You have a 10 kg mass that weighs differently in different locations. If its weight is measured as 98 N on Earth, what would be its weight on Mars where g = 3.7 m/s²?
💡 Hint: Apply the weight formula W = mg, substituting the new g for Mars.
