Gravitational force is a natural phenomenon that describes the attraction between two objects with mass. It is a fundamental force of nature that governs the motion of planets, stars, and other celestial bodies.
Gravitational force is measured using the universal law of gravitation, which states that the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
The strength of gravitational force depends on the masses of the two objects and the distance between them. The larger the masses and the closer the objects are, the stronger the gravitational force will be.
In space, gravitational force still follows the same principles as on Earth. However, the force may be weaker due to the larger distances between objects. Additionally, in space, gravitational force is responsible for the formation and movement of galaxies, stars, and other celestial bodies.
No, gravitational force cannot be shielded or canceled. It is a fundamental force of nature that exists between all objects with mass. However, its effects can be counteracted by other forces, such as the centrifugal force created by the rotation of a planet.
