2. Two objects exert a gravitational force of 4.0 N on each other.
a. If the mass of one object is doubled, what will be the new force of gravity between the two objects?
b. If both masses are doubled, what will be the new force of gravity between the objects?
c. If the masses do not change, but the distance between the objects is doubled, what will be the new force
of gravity between them?
d. If both the masses and the distance between the objects are doubled, what will be the new force of
gravity between them?
3. A 10 kg object sits on the earth's surface. What is the force of gravity between the object and the earth?
(mass of the earth = 5.97 x 1024 kg, radius of the earth = 6.37 x 106 m)

Work on each of the following problems. SHOW ALL WORK. Use g=10m/s²
4. How does your answer to the previous question compare to the force of gravity you would find by multiplying
an object's mass by the acceleration due to gravity?
5. If the earth had three times the radius but the same mass, how would this change the weight of the object?
6. If a 3 kg object is falling at terminal velocity, what upward force of air resistance does it experience?
7. A 20 kg falling object experiences 5 N of air resistance. What is the acceleration of this object?
