What is Gravity?

Gravity is the force that attracts two objects with mass towards each other. It is the force that gives weight to physical objects and is responsible for the friction between objects and the ground. The force of gravity will increase when the mass of the objects increases and vice versa; similarly, it is inversely proportional to their separation from one another. This implies that the gravitational pull between the items will be stronger the more massive they are. Similarly to this, the gravitational pull between two objects weakens with increasing distance.

The most familiar effect of gravity is the way it causes objects to fall towards the ground when they are dropped. This is because the Earth is massive compared to most objects, so it has a strong gravitational pull. All of the planets are maintained in their orbits around the Sun, and the Moon is maintained in its orbit around the Earth by the force of gravity.

The theory of general relativity, created by Albert Einstein, describes gravity as one of the fundamental forces of the world. According to this theory, gravity is not a force at all but rather a curvature of space and time caused by the presence of mass or energy. This curvature of space and time affects the motion of objects, causing them to be attracted towards the source of the gravitational force.

The planets’ orbits around the Sun and the Moon’s orbit around Earth are both kept in place by gravity. 

Gravity also draws light toward matter. Albert Einstein came up with this concept. As gravity pulls on a flashlight pointed upward, it gradually becomes redder. Scientists can measure the change even though you cannot physically see it.

Due to their strong gravitational attraction, black holes are so tightly packed with materials that even light cannot escape.
