Pure gravity refers to the fundamental force of attraction between objects with mass. It is the force that holds planets in their orbits around the sun and keeps objects on Earth's surface. It is also responsible for the formation of galaxies and the overall structure of the universe.
Pure gravity is unique because it is a universal force that affects all objects with mass. Unlike other forces, such as electromagnetism or the strong and weak nuclear forces, gravity does not require the presence of specific particles or charges to act between objects.
Pure gravity can be measured using a device called a gravimeter, which measures the acceleration of an object due to gravity. The force of gravity can also be calculated by measuring the mass and distance between two objects using the universal law of gravitation.
No, pure gravity is not the only force acting on objects. Other forces, such as friction and air resistance, also play a role in the movement and interactions of objects. However, gravity is the dominant force on a large scale, such as in the motion of planets and stars.
Currently, there is no known way to manipulate or control pure gravity. However, scientists are constantly researching and exploring theories, such as the concept of anti-gravity, in hopes of finding ways to manipulate this powerful force in the future.
