strong force
Học thuậtThân thiện
Definition
- Noun:
- The strong nuclear force: In physics, this is the fundamental force responsible for binding protons and neutrons together within the atomic nucleus. It is one of the four fundamental forces of nature and is mediated by particles called gluons.
Usage
- The term "strong force" is used specifically in the context of particle physics and nuclear physics to describe the interaction that overcomes the electrostatic repulsion between positively charged protons, thereby holding the nucleus together.
- It is a technical term and is typically used in academic, scientific, or educational discussions.
Examples
- Noun:
- The strong force is what prevents atomic nuclei from flying apart.
- Without the strong force, matter as we know it could not exist.
- Scientists study the strong force to understand the fundamental structure of matter.
Advanced Usage
- "Color force": Another name for the strong force, derived from the property of "color charge" carried by quarks and gluons in quantum chromodynamics (QCD).
- The theory describing the strong force is called Quantum Chromodynamics, and it involves the exchange of color charge.
Variants and Related Words
- Strong interaction: A synonymous term for the strong force.
- Nuclear strong force: A more specific term emphasizing its role within the atomic nucleus.
- Gluon (n): The elementary particle that mediates the strong force.
- Quantum Chromodynamics (QCD) (n): The quantum field theory that describes the strong interaction.
Synonyms
- Strong nuclear force
- Strong interaction
- Nuclear binding force
Related Phrases
- Residual strong force: The force that acts between nucleons (protons and neutrons) as a residual effect of the fundamental strong force acting between their constituent quarks.
- The residual strong force is what binds protons and neutrons together directly.
Notes
- The "strong force" is distinct from other fundamental forces: gravity, electromagnetism, and the weak nuclear force. It is the strongest of the four forces at the scale of the atomic nucleus.
- Do not confuse the "strong force" with general English adjectives like "strong." In this context, it is a fixed, compound noun with a specific scientific meaning.
Noun
- (physics) the interaction that binds protons and neutrons together in the nuclei of atoms; mediated by gluons
