    Study Notes

    Electric Current and Conductors

    • A continuous path for current flow is called a circuit.
    • Electric current in a conductor is caused by the movement of charged particles, primarily electrons.

    Energy and Particle Motion

    • The energy associated with the motion of particles within a substance is termed kinetic energy.

    Newton's Third Law of Motion

    • Newton's Third Law emphasizes that in any interaction, for every action, there is an equal and opposite reaction.

    Atomic Structure

    • According to the structure of atoms, subatomic particles (protons, neutrons, electrons) are the building blocks.

    Branches of Physics

    • Particle physics is the branch that studies fundamental particles and forces in the universe.
