Gravity is defined as

Gravity is defined as

• A. The force that repels bodies away from each other
• B. The energy stored during motion
• C. The momentum gained by force
• D. The force that attracts a body toward the center of the earth, or toward any other physical body having mass.

Answer: (D)

Gravity is the force that attracts objects with mass toward each other, pulling them toward the center of mass of the bodies involved (for everyday use, toward the Earth). This attraction explains why objects fall to the ground and why planets orbit the Sun. It is an attractive interaction, not a repulsive one, and it is not about energy stored in motion or about momentum. The other ideas mix in different concepts—repulsion would push masses apart, energy stored during motion refers to potential or kinetic energy, and momentum is mass times velocity—none of which define gravity. Gravity acts along the line between the centers of mass and weakens with distance, which underpins how celestial bodies move and how weights on Earth arise.
