Two rocks fall from the top of a 10 meter cliff. One rock has a mass of 1 kg and the other has a mass of 2 kg. Which rock has a greater gravitational attraction to Earth?
A. The 1 kg rock has a greater gravitational attraction to Earth because it has less mass.
B. The 1 kg rock has a greater gravitational attraction to Earth because it has more mass.
C. The 2 kg rock has a greater gravitational attraction to Earth because it has less mass.
D. The 2 kg rock has a greater gravitational attraction to Earth because it has more mass.

B. put people in the car
C. start the car engine
D. take the tires off of the car
Newton’s Law of Universal Gravitation dictates the relationship between the masses of two objects, the distance between them, and the resulting force of gravitational attraction. If the mass of one object becomes twice as large, how will this affect its gravitational force on another object?
