Gravity - Page 6
Gravity is a fundamental force of nature that attracts two bodies with mass towards each other. It is responsible for keeping objects anchored to the Earth, governing the motion of planets, stars, galaxies, and even light. The strength of gravitational attraction depends on the masses of the objects involved and the distance between them, as described by Isaac Newton’s law of universal gravitation. In everyday life, gravity gives weight to physical objects and influences various natural phenomena such as ocean tides, free fall, and orbital motions. Additionally, Albert Einstein's theory of general relativity explains gravity as the curvature of spacetime caused by mass, providing a deeper understanding of how gravity operates in the universe.
