Fundamental Forces and Particles Quiz

Matter composed of antiparticles, which have opposite charges to particles.

A particle that has the opposite charge of its corresponding particle.

Process where a particle and its antiparticle destroy each other, converting mass into energy.

The basic forces: strong nuclear, electromagnetic, weak nuclear, gravitational influencing interactions.

A type of radioactive decay involving the weak nuclear force, changing protons and neutrons.

A particle with no internal structure that can't be divided.

Particles affected by strong nuclear force; examples are protons and neutrons.

Particles not affected by strong nuclear force; examples include electrons and neutrinos.

A force that holds quarks together in hadrons.

The force that affects charged particles including hadrons and leptons.

A force responsible for certain particle decays.

A particle that explains why other particles have mass.

A fundamental particle that makes up hadrons.

There are six types: up, down, charm, strange, top, bottom.

The up quark has a charge of +2/3 elementary charge (e).

A particle with the opposite charge of its corresponding quark.

A theory describing the fundamental particles and their interactions.

The down quark has a charge of -1/3 elementary charge (e).

Experiments that reveal the existence of hadrons and quarks.

A particle made of two up quarks and one down quark (uud), with a charge of +1e.

A particle made of one up quark and two down quarks (udd), with no charge.

The principle that total charge in an isolated system remains constant.

The proton consists of two up quarks and one down quark (uud).

The neutron consists of one up quark and two down quarks (udd).

Hadrons composed of three quarks, including protons and neutrons.

Hadrons made of a quark and an anti-quark.

The total charge is zero for a particle made of uds combination.

Quarks that carry a positive charge: up quark (+2/3)e.
