"Energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light."
Study of work, heat, and energy transformations.
Kinetic Energy: Energy that an object possesses due to its motion.
Potential Energy: Energy that an object possesses due to its position relative to other objects.
Mechanical Energy: The sum of an object's kinetic and potential energy.
Thermal Energy: Energy associated with the random motion of atoms and molecules in a material.
Heat: Transfer of thermal energy from a warmer object to a cooler object.
Work: Transfer of energy to or from an object by means of a force acting on the object.
Conservation of Energy: The law that states that energy cannot be created or destroyed, only transformed from one form to another.
Power: The rate at which energy is transferred or transformed.
Energy Sources: Various natural resources, such as fossil fuels and renewable energy sources, that can be used to generate energy.
Energy Transfer: The process by which energy is exchanged between objects or systems.
Energy Conversion: The process of converting one form of energy into another.
"The law of conservation of energy states that energy can be converted in form, but not created or destroyed."
"The unit of measurement for energy in the International System of Units (SI) is the joule (J)."
"Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object, the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system."
"All living organisms constantly take in and release energy."
"Any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy."
"Any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy."
"Human civilization requires energy to function, which it gets from energy resources such as fossil fuels, nuclear fuel, or renewable energy."
"The Earth's climate and ecosystems processes are driven by the energy the planet receives from the Sun."
"A small amount [of energy] is also contributed by geothermal energy."
"Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity')"
"Energy is recognizable in the performance of work and in the form of heat and light."
"Energy can be converted in form, but not created or destroyed."
"The potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, and the internal energy contained within a thermodynamic system."
"Energy resources such as fossil fuels, nuclear fuel, or renewable energy."
"The unit of measurement for energy in the International System of Units (SI) is the joule (J)."
"Any additional energy acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy."
"The energy the planet receives from the Sun" contributes significantly, whereas "a small amount is also contributed by geothermal energy."
"Energy is transferred to a body or to a physical system, recognizable in the performance of work."
"All living organisms constantly take in and release energy." Note: The quotes provided are paraphrased for brevity while retaining the essence of the original information.
