Three quarks sit inside every proton. The strong force binds them, and it is the strongest force there is. How does that grip get from quark to quark?
The answer repeats the photon's story, with the actors changed. Recall the photon's sentence: charged particles interact by exchanging photons.
The three quarks inside a proton stay bound because they constantly exchange gluons. The name fits: gluons are the glue that holds the proton together.
The three quarks inside a neutron stay bound together. Which particle are they exchanging?
The strong force binds quarks.
Quarks interact by exchanging gluons.
The quarks inside the neutron exchange gluons.
Which particle do quarks exchange when they interact?
Which force does the gluon carry?
How do quarks exert the strong force on one another?
Two quarks exert the strong force on each other. Which boson passes between them?
Which particles interact by exchanging gluons?
A student says the quarks inside a proton are bound by exchanging photons. Which particle do the quarks actually exchange?
