Gravity is the force of attraction between all objects with mass, and on Earth, it causes objects to accelerate downward at approximately 9.8 meters per second squared (m/s²), or about 1 g. While gravity is the weakest of the four fundamental forces in nature—much weaker than the strong nuclear force, electromagnetic force, and weak nuclear force—it dominates on large scales like planets and galaxies because it has an infinite range and only attracts (no negative mass). Earth's gravity varies slightly depending on location due to factors like the planet's rotation and variations in mass distribution beneath the surface. At the equator, gravity is about 9.789 m/s², while at the poles, it is about 9.832 m/s². The average standard gravity value used is 9.80665 m/s². In everyday terms, this means the speed of a falling object increases by about 9.8 meters per second every second ignoring air resistance. Despite being weak compared to other forces, Earth's gravity is strong enough to hold everything on its surface and govern the motion of celestial bodies.
