Answer: Astronauts are in continuous free fall around Earth, meaning they are moving forward at a speed that keeps them falling around the planet. Since both they and their spacecraft are accelerating equally under gravity, they do not feel weight; this condition is known as apparent weightlessness. Exercise 2: Calculation Question: Calculate the gravitational force between the Sun (\( 1.989 \times 10^{30} \) kg) and Earth (\( 5.972 \times 10^{24} \) kg), given that the average distance between them is about 149.6 million km.
