Which statement describes the Law of Gravitation?

• A. Every particle attracts forces proportional to their mass
• B. Energy is conserved in all reactions
• C. The universe began in a dense, hot state
• D. Objects accelerate equally in all frames

Answer: (A)

Gravitation is about how mass causes an attractive force between objects, with the strength growing as the masses get larger and weakening as the objects move farther apart. The statement that every particle attracts forces proportional to their mass captures that mass dependence of gravity, which is the key idea Newton described: gravity pulls harder when there are bigger masses involved. (In full form, the force also depends on the distance between the masses, shrinking with the square of that distance, but among the options this one best reflects how mass drives the attraction.) The other choices describe energy conservation, the origin of the universe, or an idea about acceleration across frames that doesn’t describe gravity, so they don’t fit as explanations of the Law of Gravitation.
