The force that pulls objects towards the center of the Earth, resulting in the weight that is felt by those objects, which varies slightly depending on geographical location.
A combination of gravitational forces resulting from both the Earth's mass and its rotation, causing a measurable acceleration experienced by objects on Earth.
A fundamental force governing the attraction between masses, particularly significant on Earth, and influencing the movement and behavior of objects in both terrestrial and cosmic contexts.
Example:
月の重力は地球の６分の１である。
A state in which gravitational forces are absent, allowing objects to float freely without the effects of weight.
The condition experienced by astronauts in space, where the sensation of gravity is significantly diminished, leading to a feeling of floating.
The phenomenon that occurs when the acceleration of an object in freefall cancels out the force of gravity acting on it, resulting in no apparent weight.
Example:
その宇宙飛行士は無重力の状態になかなか慣れなかった。
An environment in which the effects of gravity are significantly reduced, resulting in the sensation of floating or having no weight.
A physical condition experienced in space or during free fall, where objects appear to be weightless and can move freely without the influence of gravitational forces.
A phenomenon that occurs in specific circumstances, such as in orbit around the Earth, where the force of gravity is countered by the motion of an object, leading to the absence of perceived weight.
The region around an object where its gravitational pull influences other masses, affecting their motion and orientation.
A spatial framework characterized by the force of gravity, wherein objects experience an attraction towards a central mass.
An area defined by the presence of gravitational forces, where the strength and direction of gravity can vary depending on the mass and distance from the source.
The conceptual space in which the effects of gravity are observed, significant for understanding the behavior of celestial bodies and objects in motion.
A theoretical elementary particle that mediates the force of gravity in quantum field theory, believed to be responsible for the attraction between masses.
A fundamental entity in the framework of quantum mechanics that is proposed to exist in order to explain gravitational interactions at the subatomic level.
An envisioned particle that travels at the speed of light and carries the gravitational force, associated with the exchange of gravitational energy between objects with mass.
A concept in theoretical physics that represents the quantum counterpart of the classical force of gravity, serving to unify gravitational phenomena with other fundamental forces.
