What are Forces？(力的相互作用-美国康菲尔高中)
What are the 3 forces of nature? The Four Fundamental Forces of Nature areGravitational force, Weak Nuclear force, Electromagnetic force and Strong Nuclear force. The weak and strong forces are effective only over a very short range and dominate only at the level of subatomic particles. What ar...

Examples of non-contact forces are: Gravitational Force Electrostatic Force Magnetic Force The force exerted by a magnet on other magnets is called magnetic force. Magnetic force and electrostatic force act on an object from a distance. That’s the reason they are non-contact forces. The strength...
"New productive forces are crucial to promote self-reliance in high-level science and technology," said Yuan Yuyu, NPC deputy and chairman of Medprin Regenerative Medical Technologies Co., Ltd, adding that his focus at the "two sessions" will be how to strengthen sci-tech innovation, especially...
If you are a fan of science fiction, then you know that "relativity" is a fairly common part of the genre. For example, people on Star Trek are always talking about the space-time continuum, worm holes, time dilations and all sorts of other things that are based on the principle of ...
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...
NEW QUALITY PRODUCTIVE FORCES Stroll through the Hefei Hi-tech Zone and expect to see the birthplace of the world's first quantum science experiment satellite, "Mozi," the country's first quantum chip production line and the world's leading voice recognition system. ...
