Keywords

💡Fundamental Forces

Fundamental forces are the basic interactions that govern the behavior of all matter in the universe. In the video, the concept is introduced to explain the different types of forces that cannot be interchanged or reduced to any other interactions. For example, the script mentions 'Fundamental Forces' or 'Fundamental Inductions' as the forces that cannot be exchanged between particles, such as gravitational, electromagnetic, and nuclear forces.

💡Fundamental Quantities

Fundamental quantities refer to properties that cannot be broken down into simpler components or exchanged between particles. In the context of the video, the script explains that fundamental quantities like mass and length cannot be interchanged, which is why they are called fundamental. They are the basic building blocks of matter and are intrinsic to the particles themselves.

💡Gravitational Force

Gravitational force is one of the four fundamental forces in physics, which causes attraction between masses. The script describes it as a long-range force that acts over vast distances, such as the attraction between celestial bodies like the Earth and the Sun. It is responsible for the formation of galaxies and the structure of the universe.

💡Electromagnetic Force

Electromagnetic force is another fundamental interaction that governs the behavior of charged particles. The video script discusses it in the context of long-range forces, similar to gravitational force, and explains how it can cause both attraction and repulsion between particles based on their charge.

💡Nuclear Force

Nuclear force, also mentioned as strong force in the script, is responsible for binding protons and neutrons together within the atomic nucleus. It is a short-range force that is much stronger than gravitational and electromagnetic forces but acts only over very small distances within the nucleus.

💡Elementary Particles

Elementary particles are the fundamental constituents of matter that cannot be broken down into smaller particles. The script refers to elementary particles like protons, neutrons, and electrons, which are the building blocks of atoms and are involved in various fundamental interactions.

💡Strong Interaction

Strong interaction, also known as the strong nuclear force, is what holds quarks together to form protons and neutrons. The video script touches on this concept when discussing the strong force that keeps particles within the nucleus and is responsible for the stability of atomic nuclei.

Electromagnetic induction is the process by which a changing magnetic field induces an electric current in a conductor. The script briefly mentions this concept in the context of electromagnetic force and its effects on charged particles, which is a fundamental principle in electromagnetism.

💡Gravitational Dynamics

Gravitational dynamics refers to the study of the motion of celestial bodies under the influence of gravity. The video script uses this term to describe the long-range attractive force of gravity and its role in shaping the universe's large-scale structure.

💡Nuclear Dynamics

Nuclear dynamics involves the study of the behavior and interactions of particles within atomic nuclei. The script hints at this when discussing nuclear forces and their role in maintaining the stability of atomic nuclei against the repulsive electromagnetic force between protons.
