What phenomenon is described by Newton’s Law of Universal Gravitation?

Friction
Reflection
Attraction
Refraction

The correct answer is: Attraction

Newton's Law of Universal Gravitation describes the force of gravitational attraction between two objects that have mass. Friction, reflection, and refraction are not related to this law and therefore incorrect choices. Friction is a force that opposes motion, reflection is the change in direction of a wave on a surface, and refraction is the bending of light as it passes through different mediums. None of these concepts relate to the phenomenon described by Newton's Law of Universal Gravitation.
