In physics, gravity is a fundamental interaction which causes all things with mass or energy to be attracted toward one another. Gravity is by far the weakest of the four fundamental interactions, approximately 10³⁸ times weaker than the strong interaction, 10³⁶ times weaker than the electromagnetic force and 10²⁹ times weaker than the weak interaction. As a result, it has no significant influence at the level of subatomic particles. However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes tides in the oceans. Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms.

It peaked at the number 71 spot on the US Billboard Hot 100 chart. The song's audio has been streamed more than 12.5 million times on YouTube.
您不知道Gravity的热门事实
Anti-gravity, the idea of neutralizing or repelling gravity.. Artificial gravity - Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation.. Gauss's law for gravity - In physics, Gauss's law for gravity, also known as Gauss's flux theorem for gravity, is a law of physics that is essentially equivalent to Newton's law of universal gravitation. It is named after Carl Friedrich Gauss.. Gravitational potential - In classical mechanics, the gravitational potential at a location is equal to the work per unit mass that would be needed to move an object to that location from a fixed reference location. It is analogous to the electric potential with mass playing the role of charge.. Micro-g environment, also called microgravity.. Newton's laws of motion - Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.. Empirical laws.. Acceleration.
