raskusjõud
Raskusjõud, also known as gravitational force, is a fundamental force of nature that attracts any two objects with mass. It is responsible for keeping planets in orbit around stars, holding galaxies together, and causing objects to fall to the ground. The strength of the gravitational force between two objects depends on their masses and the distance between them. More massive objects exert a stronger gravitational pull, and the force weakens as the distance between the objects increases. This relationship is described by Newton's law of universal gravitation, which states that the force of gravity is directly proportional to the product of the two masses and inversely proportional to the square of the distance between their centers. On Earth, raskusjõud is what gives objects weight. The Earth's large mass creates a significant gravitational pull on everything on its surface, pulling them towards its center. This force is what we experience as weight. While gravity is a universal force, its effects are most noticeable with celestial bodies due to their immense masses. The concept of raskusjõud has been crucial in understanding the mechanics of the universe and has been a cornerstone of physics for centuries.
