    Study Notes

    Energy Overview

    • Energy is the capacity to do work or produce change in a system.
    • It exists in various forms, including kinetic, potential, thermal, chemical, and nuclear energy.

    Types of Energy

    • Potential Energy: Associated with the relative position of an object, determined by its height and mass in a gravitational field.
    • Kinetic Energy: The energy of motion, dependent on the mass and speed of an object.

    Temperature and Thermal Energy

    • Temperature: A quantitative measure of the average kinetic energy of particles in a substance, reflecting how hot or cold it is.
    • Thermal Energy: The total internal energy of a system due to the kinetic energy of its particles. It increases with temperature.

    Energy Conversion

    • During energy conversion, energy changes from one form to another, but the total energy is conserved (according to the law of conservation of energy).
    • Examples include transforming potential energy into kinetic energy or converting electrical energy into thermal energy.
