Newton's Gravitational Law

Which of these best describes why your weight (on Earth) would change on another planet?

• Dehydration effects on different planets change weight.

• In general, the smaller the planet, the greater weight

• Different planets have different gravitational pulls

• Weight does not change, no matter where you are.

Which of the following best describes Newton's Law of Universal Gravitation?

• It states that every object in the universe attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

• It states that every object in the universe repels every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

• It states that every object in the universe attracts every other object with a force proportional to the sum of their masses and inversely proportional to the square of the distance between them.

• It states that every object in the universe attracts every other object with a force proportional to the product of their masses and directly proportional to the distance between them.
