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.
