How does gravity work

1 answer

Gravity is the force that attracts two objects with mass towards each other. It is responsible for the phenomenon of weight and keeps objects grounded on Earth. Gravity works based on the principle of mass attracting mass.

According to Albert Einstein's theory of general relativity, gravity is the result of the curvature of spacetime caused by the presence of mass and energy. Objects with mass are capable of warping the fabric of spacetime, and the more massive an object is, the stronger its gravitational pull.

In simpler terms, gravity works by creating a force that pulls objects closer together. The force of gravity between two objects depends on two factors: the masses of the objects and the distance between them. The larger the masses of the objects, the stronger the gravitational force, and the closer the objects are to each other, the stronger the gravitational force.

This force of gravity acts in all directions, meaning that every object in the universe attracts every other object with mass. However, the force becomes weaker as the distance between the objects increases. This is why we primarily feel the gravitational pull of larger objects like the Earth and the Sun, as their masses are significantly greater than ours.

Gravity is the reason why planets orbit around the Sun, why the Moon orbits around the Earth, and why objects fall to the ground when they are dropped. It is a fundamental force of nature that shapes the structure of the universe and plays a crucial role in the interactions between celestial bodies and everyday objects.
