Detailed explanation-1: -Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

Detailed explanation-2: -Gravity is the force that pulls all objects in the universe toward each other. On Earth, gravity pulls all objects “downward” toward the center of the planet.

Detailed explanation-3: -Weight measures the force of gravity pulling on an object. The SI unit for weight is the Newton (N).

Detailed explanation-4: -In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.
