Question: Answer the following question given this paragraph: All objects in the universe have a gravitational attraction to each other ( Figure below ). The strength of the force of gravity depends on two things. They are the mass of the objects and the distance between them. The greater the objects' mass, the greater the force of attraction. As the distance between the objects increases, the force of attraction decreases. Q: The mass of the objects and the distance between them affect the strength of what universal force? Choices: - states of matter - weight - motion - gravity A:
Answer:
gravity
