Weak Interaction The Four Fundamental Forces of Physics #2

The video explores the weak force, one of the four fundamental forces in physics, which operates over very short distances. It plays a crucial role in processes like the sun's energy production and carbon-14 dating. The weak force changes the flavor of quarks, affecting particle identity. It interacts with quarks and leptons, involving force carriers like W and Z bosons. An example of weak interaction is shown where a neutron decays into a proton, illustrating the force's ability to change atomic structure.

What role does the weak force play in the universe?

• It causes earthquakes.

• It holds the planets in orbit.

• It is responsible for the sun's shining and carbon-14 dating.

• It creates magnetic fields.

How does the weak force differ from the strong force in terms of quark interaction?

• The weak force changes quark colors.

• The weak force changes quark flavors.

• The weak force only affects electrons.

• The weak force does not interact with quarks.

Which of the following is NOT a flavor of quark?

• Lemon

• Charm

• Down

• Up

What are the force carriers involved in the weak force?

• Protons and Neutrons

• Electrons and Neutrinos

• W and Z bosons

• Photons and Gluons

What happens when a neutron decays into a proton through the weak force?

• The atom gains an electron.

• The atom loses mass.

• The atom becomes a different element.

• The atom remains unchanged.
