Energy is the capacity to do work or produce heat. It is a fundamental concept in physics that can take various forms such as potential, kinetic, or thermal energy.

Common units of energy include joules, calories, and electronvolts. Work is the transfer of energy through the application of force over a distance. Torque is a measure of the rotational force on an object. Heat is the transfer of energy between systems due to a temperature difference. Spectral flux (fr) is the amount of energy flowing through a unit area per unit time per unit wavelength.

  • Energy is essential for all forms of work and motion.
  • Work is needed to accomplish tasks and move objects.
  • Torque is crucial for rotating machinery and engines.
  • Heat transfer is important in various processes such as cooking and heating.
  • Spectral flux is used in astronomy to study the energy emitted by stars.
