Step 1:Let's solve this step by step:
Step 2:: Understand Newton's Law of Universal Gravitation
Newton's law of universal gravitation states the fundamental principle of gravitational attraction between objects in the universe.
Step 3:: Analyze the Key Components of the Law
The law describes that: - Every object with mass exerts a gravitational force on every other object - The force depends on the masses of the two objects - The force is proportional to the product of the masses - The force is inversely proportional to the square of the distance between the objects
Step 4:: Evaluate Each Option
A. Mass has little effect on gravity between objects - INCORRECT: Mass is actually crucial in determining gravitational force B. Gravity pushes objects away from Earth's center - INCORRECT: Gravity pulls objects toward the center, not pushes them away C. Gravity does not act between Earth and the moon - INCORRECT: Gravity is precisely what keeps the moon in orbit around Earth D. Every object in the universe attracts every other object - CORRECT: This directly describes the core principle of Newton's law of universal gravitation
Step 5:: Confirm the Mathematical Representation
- $$r$$ is the distance between the objects
The law can be expressed mathematically as: Where:
Final Answer
Every object in the universe attracts every other object
