mechanical energy
In the physical sciences, mechanical energy is the sum of potential energy and kinetic energy
A system is a set of interacting or interdependent component parts forming a complex/intricate whole
electromagnetic spectrum
The electromagnetic spectrum is the collective term for all known frequencies and their linked wavelengths of the known photons
In physics, energy is a property of objects which can be transferred to other objects or converted into different forms
In physics, heat is energy that spontaneously passes between a system and its surroundings in some way other than through work or the transfer of matter
kinetic energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion
Thermal energy
In thermodynamics, thermal energy refers to the internal energy present in a system due to its temperature
A photon is an elementary particle, the quantum of all forms of electromagnetic radiation including light
Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz and 300 GHz
visible light
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye
greenhouse effect
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere
In physics, a force is said to do work if, when acting there is a displacement of the point of application in the direction of the force
Geothermal energy is thermal energy generated and stored in the Earth
absolute zero
Absolute zero is the lower limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as 0
A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence
Stefan-Boltzmann Law
The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature
In radiometry, irradiance is the radiant flux received by a surface per unit area
