Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. What does Newton's Law of Universal Gravitation state about the force between two objects?
Directly proportional to the distance between them.
Inversely proportional to the product of their masses.
Directly proportional to the product of their masses.
Inversely proportional to the square of their masses.
2. The gravitational constant (G) has a value of approximately:
9.8 m/s²
6.67 x 10⁻¹¹ N·m²/kg²
3.0 x 10⁸ m/s
1.6 x 10⁻¹⁹ C
3. The force of gravity is always between any two objects with mass.
4. According to Newton's Law of Gravitation, if the distance between two objects doubles, the gravitational force between them will be as strong.
5. The gravitational force between two objects depends on the medium separating them.
True
False
6. Gravity is considered a long-range force.
True
False
7. State the formula for Newton's Law of Universal Gravitation and define each variable.
8. Explain why the gravitational force between everyday objects on Earth is negligible, while the gravitational force between Earth and the Moon is significant.
9. Two objects, one with a mass of 50 kg and the other with a mass of 100 kg, are separated by a distance of 2 meters. Calculate the gravitational force between them. (G = 6.67 x 10⁻¹¹ N·m²/kg²)
