gravitationally

gravitationally的音标是[ˌgrævɪˈteɪʃənəli]。这个单词的意思是“在重力方面；在引力方面”。速记技巧可以是：gravity的重读加上tely。

"gravitationally" 这个词的英文词源可以追溯到拉丁语 "gravis"（重的）和 "tendere"（倾向于）。它的意思是“在重力作用下”。

变化形式：在复数形式中，"gravities" 指的是重力、引力。

Gravity: The Universal Force

Gravity is a fundamental force of nature that affects everything we do and exist in our universe. It binds celestial bodies together, determines the motion of planets and moons, and creates the atmosphere of our planet. Without gravity, objects would fly away into space, and life as we know it would be impossible.

Gravity is a result of the attraction between massive objects, caused by their inherent mass and energy. When two objects with sufficient mass are close enough to each other, they exert a force on each other that is proportional to their masses and inversely proportional to the square of the distance between them. This force is what keeps us on the ground, keeps our planet rotating, and keeps everything in its place.

Gravity plays an essential role in our daily lives. We rely on it to support our weight while we walk, run, and even fly in airplanes and spacecrafts. It determines the shape of the Earth, creating the tides and ocean currents, and influences the motion of celestial bodies such as asteroids and comets. Understanding gravity is crucial for understanding our universe and for developing technologies that rely on it, such as satellite navigation and precision measurement instruments.
