Graviteerimine

Graviteerimine is a concept in physics that refers to the process by which an object moves under the influence of gravity alone, without any other external forces acting upon it. This type of motion is commonly observed in the context of free fall, where an object is released from a certain height and allowed to fall to the ground. The motion of the object can be described using the equations of motion derived from Newton's laws of motion and the universal law of gravitation.

In a vacuum, where air resistance is negligible, the motion of an object in free fall is purely gravitational. The object accelerates at a constant rate, known as the acceleration due to gravity, which is approximately 9.8 meters per second squared on the surface of the Earth. This acceleration causes the velocity of the object to increase linearly with time, and the distance it travels to increase quadratically with time.

Graviteerimine is also relevant in the context of orbital mechanics, where the gravitational force between two objects, such as a planet and a satellite, causes the satellite to move in a curved path around the planet. The motion of the satellite can be described using Kepler's laws of planetary motion, which provide a mathematical description of the orbits of celestial bodies.

In summary, graviteerimine is the process by which an object moves under the influence of gravity alone. This concept is fundamental to our understanding of the motion of objects in the natural world, from the motion of a falling apple to the orbits of planets and satellites.
