Question

Which of the following can be explained by the universal law of gravitation?

• A. The force that is responsible for binding us to the Earth.
• B. The motion of the Moon around the Earth.
• C. The motion of planets around the Sun.
• D. All of the above

Answer 1

The correct option is D

All of the above

The force in all these cases is the gravitational force, and it is explained by the universal law of gravitation.

Newton's law of universal gravitation states that an object attracts every other object in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.
