Law of Universal Gravitation

Instructions: Read each question carefully. Choose the answer that best fits the question. Short answer response questions must be responded to in complete sentences. If the question involves calculations, you must show all your math work.
Given:
[math]G=6.67xx10^−11 N(m/kg)^2[/math] and [math]F_g=(Gm_1m_2)/(r^2)[/math]

1. 
What does the law of universal gravitation state?



2. 
The English mathematician and scientist who formulated the law of universal gravitation was
  1. Galileo
  2. Newton
  3. Huygens
  4. Cavendish
3. 
According to the Law of Universal Gravitation, the gravity of the planet Mercury actually has some effect on you even though it is extremely small.
  1. True
  2. False
4. 
What effect does distance have on the strength of the force of gravity?
  1. Smaller the distance, the weaker the gravitational pull
  2. distance and force are not related
  3. greater the distance, the weaker the gravitational pull
  4. greater the distance, the stronger the gravitational pull
5. 
What is the inverse square rule as it relates to distance and the force of gravity?



6. 
As objects move, the force of gravity changes its direction to stay pointed along the line between their centers.
  1. True
  2. False
7. 
Two students are sitting 1.50 m apart. One student has a mass of 70.0 kg and the other has a mass of 52.0 kg. What is the gravitational force between them?
  1. [math]1.62xx10^-7N[/math]
  2. [math]8.09xx10^8N[/math]
  3. [math]1.08xx10^-7N[/math]
  4. [math]1.09xx10^7N[/math]
8. 
Calculate the gravitational force between two objects when they are [math]7.50xx10^-1m[/math] apart. Each object has a mass of [math]5.00xx10^1kg[/math].
