What is the universal force of attraction between any two objects called?

• A. friction
• B. gravity
• C. magnetism
• D. inertia

Answer: (B)

Gravity is the universal force of attraction between any two objects with mass. It acts at a distance, pulling them toward each other, and its strength depends on how large the masses are and how close they are: bigger masses and shorter distances mean a stronger pull. This is why we feel Earth's gravity pulling us toward the ground, and why planets orbit the Sun. Other forces listed—friction is a contact force that resists motion between surfaces; magnetism arises from magnetic fields between certain materials or moving charges; inertia is not a force but the tendency of objects to resist changes in their motion.
