Question 1
A satellite orbits Earth at a height where the acceleration due to gravity is 8 m/s². If the mass of the satellite is 2000 kg, calculate its weight in Newtons.
💡 Hint: Use the weight formula with the given acceleration due to gravity.
Question 2
Consider a person weighing 600 N on Earth. Calculate their mass, then determine their weight on Mars, where gravity is about 3.71 m/s².
💡 Hint: First, find mass using the weight on Earth, then calculate the new weight using Mars' gravity.
