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?
Every object in the universe attracts every other object 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.
Gravity only acts on celestial bodies.
The force of gravity is constant everywhere in the universe.
The gravitational force is inversely proportional to the product of their masses.
2. If the distance between two objects is doubled, the gravitational force between them will be:
Doubled
Halved
Quartered
Quadrupled
3. The constant G in the universal gravitation equation is known as the constant.
4. The gravitational force between two objects depends on their masses and the between them.
5. State the formula for Newton's Law of Universal Gravitation and define each variable.
6. The acceleration due to gravity is the same for all objects on Earth, regardless of their mass.
True
False
7. Calculate the gravitational force between the Earth (mass = 5.97 x 10^24 kg) and the Moon (mass = 7.35 x 10^22 kg) if the average distance between their centers is 3.84 x 10^8 meters. (G = 6.674 × 10^-11 N(m/kg)^2)
