Forms of Energy Flashcards
Energy
Ability to perform work
Mechanical Energy
Energy of movement
Chemical Energy
Energy stored in chemical bonds
Nuclear Energy
Energy stored in the nucleus of an atom
Also called Atomic energy
Thermal Energy
Total kinetic energy that an object’s molecules possess
Heat
Electrical Energy
Flow of electrons
Magnetism
Attractive and repelling forces contained in magnetic materials
Sound Energy
Energy that travels in waves through matter such as air, water, or wood and can be detected by the human ear
Light Energy
Electromagnetic waves that can be detected by the eye
First Law of Thermodynamics
Mass and energy can not be create or destroyed; only change forms
Kinetic Energy
Energy that is being used
Potential Energy
Energy that is being stored
Photosynthesis
Reaction inside plants that combine water, carbon dioxide, and sunlight to produce sugar and oxygen.
Fossil Fuels
Petroleum products formed from the remains of plants and animals that were burned in the past and placed under pressure
Cellular Resperation
Process that breaks down sugar molecules to release the stored energy
Also called digestion
Combustion
Releasing of energy through burning
Bioenergy
Energy that comes from plants and animal matter
Fission
Breaking apart of the nucleus into smaller nuclei
Fusion
Combining of nuclear particles to form a larger nucleus
Radioactive
Material with an unstable nucleus
Alpha Particles
Two protons and two neutrons with no electrons
Beta Particles
Very high-speed electron
Gamma Radiation
Very energetic electromagnetic radiation
Atomic Bomb
Weapon powered by fission
Hydrogen Bomb/ Thermonuclear Bomb
Weapon powered by fusion
Radioactive Decay
Process where by a nucleus releases radioactive particles and energy
Radiometric Dating
Measuring the amount of radioactive elements in a substance to determine its age
