Which term is the fundamental force responsible for the attraction between masses?

• A. Gravitational forces
• B. Electromagnetic forces
• C. Strong nuclear force
• D. Weak nuclear force

Answer: (A)

Gravity is the force that makes masses pull on one another. It’s a universal, always-attractive interaction, different from electromagnetic forces, which can attract or repel depending on charge. The strong and weak nuclear forces act inside atomic nuclei and don’t govern the attraction between everyday masses. In Newtonian terms, gravitational force falls off with the square of the distance and is described by gravity, the fundamental force responsible for this attraction.
