Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. According to Newton's Law of Universal Gravitation, the gravitational force between two objects is directly proportional to:
The distance between their centers
The square of the distance between their centers
The product of their masses
The sum of their masses
2. What is the approximate value of the universal gravitational constant (G)?
9.8 m/s²
6.67 x 10⁻¹¹ Nm²/kg²
3.0 x 10⁸ m/s
1.6 x 10⁻¹⁹ C
3. The force of gravity is an force, meaning it always pulls objects together.
4. The acceleration due to gravity on Earth's surface is approximately .
5. The gravitational force between two objects increases as the distance between them increases.
True
False
6. Mass and weight are interchangeable terms.
True
False
7. State Newton's Law of Universal Gravitation in words and write its mathematical formula.
8. 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 0.5 meters apart. (G = 6.67 x 10⁻¹¹ Nm²/kg²)
