Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best describes Newton's Law of Universal Gravitation?
Gravity is directly proportional to the square of the distance between objects.
Gravity is inversely proportional to the product of the masses of objects.
Every particle attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The gravitational force depends only on the mass of the larger object.
2. The universal gravitational constant is represented by the letter G, and its approximate value is .
3. Gravitational force is always an force, meaning it pulls objects together.
4. If the distance between two objects doubles, the gravitational force between them becomes of its original value.
5. The gravitational force between two objects depends on the medium separating them.
True
False
6. Explain the relationship between mass and gravitational force. How does increasing the mass of one object affect the gravitational force between it and another object?
7. Two spherical objects have masses of 5 kg and 10 kg, respectively. Their centers are separated by a distance of 0.5 meters. Calculate the gravitational force between them. (Use G = 6.67 × 10⁻¹¹ N·m²/kg²)
