Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following statements best describes Newton's Law of Universal Gravitation?
Gravity is directly proportional to the distance between two objects.
Gravity is inversely proportional to the product of the masses of two objects.
Gravity is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
Gravity is a force that only acts on objects in direct contact.
2. What is the approximate value of the gravitational acceleration (g) near the Earth's surface?
1.6 m/s²
9.8 m/s²
27.4 m/s²
0 m/s²
3. The force of gravity between two objects is directly proportional to the product of their and inversely proportional to the square of the between their centers.
4. The universal gravitational constant, represented by the symbol G, has a value of approximately N·m²/kg².
5. Explain the concept of weightlessness in orbit. Is an astronaut in the International Space Station truly weightless?
6. The force of gravity on an object decreases as its distance from the center of the Earth increases.
True
False
7. Calculate the gravitational force between two spheres, one with a mass of 10 kg and the other with a mass of 20 kg, if their centers are separated by a distance of 0.5 meters. (G = 6.674 × 10⁻¹¹ N·m²/kg²)
8. Observe the image below of an astronaut experiencing 'zero gravity'. In the context of gravity, explain why the term 'zero gravity' is a common misconception.
