FLASHCARD QUESTION

Front

Gravity Noun

[grav-i-tee]

Back

Gravity


A fundamental force of attraction that exists between all objects with mass, dominant at large astronomical scales.

Example: This diagram shows how a planet's orbit is a balance between its forward 'sideways motion' and the inward 'pull of gravity' from a star.

Electromagnetism Noun

[uh-lek-tro-mag-nuh-tiz-uhm]

Back

Electromagnetism


A fundamental force governing interactions between electrically charged particles, responsible for electricity, magnetism, and chemical bonds.

Example: Wrapping a wire carrying an electric current from a battery around an iron nail creates a magnetic field, turning the nail into an electromagnet.

FLASHCARD QUESTION

Front

Strong Force Noun

[strong fors]

Back

Strong Force


The strongest of the four fundamental forces, which binds quarks together to form protons and neutrons.

Example: The strong nuclear force is an attractive force that holds protons and neutrons together in the nucleus, overcoming the electrostatic repulsion between positively charged protons.

FLASHCARD QUESTION

Front

Weak Force Noun

[week fors]

Back

Weak Force


A fundamental force that governs the radioactive decay of subatomic particles and initiates processes like nuclear fusion.

Example: The weak force causes a neutron to change (decay) into a proton, an electron, and an antineutrino.

FLASHCARD QUESTION

Front

Nucleus Noun

[noo-klee-uhs]

Back

Nucleus


The dense, positively charged central region of an atom, which is composed of protons and neutrons.

Example: The nucleus is the central part of an atom, containing positively charged protons and neutral neutrons, all held together by strong nuclear forces.

FLASHCARD QUESTION

Front

Quark Noun

[kwark]

Back

Quark


An elementary particle and a fundamental constituent of matter that combines to form composite particles called hadrons.

Example: This diagram shows that quarks are fundamental particles that combine to form larger particles, like a proton, which is made of two 'up' quarks and one 'down' quark.

FLASHCARD QUESTION

Front

Meson Noun

[mee-zon]

Back

Meson


A subatomic particle composed of one quark and one antiquark, which are bound together by the strong force.

Example: This diagram shows that a meson (like a pion) is a particle made of one quark and one antiquark bound together.
