Gravity Explained

Gravity is a fundamental force that governs how objects with mass interact across space. It explains why objects fall toward the Earth and why planets orbit stars. Gravity influences the motion of moons, asteroids, and galaxies throughout the universe. On Earth, gravity affects everyday activities, from walking to the flow of water in rivers. Isaac Newton described gravity as a force acting at a distance between masses. Later, Albert Einstein showed that gravity results from the curvature of spacetime. Gravity is essential for the formation of stars and the stability of solar systems. It also causes tides due to the gravitational pull of the Moon and Sun. Modern science studies gravity using physics, astronomy, and cosmology. Understanding gravity helps advance space exploration and satellite technology.
