characteristics of energy Flashcards
what are the characteristics of energy
matter is composed of substances that occupy space and have a mass.
energy is made up of particles that do not occupy space or have a mass.
energy is the ability to do work.
energy has different properties from those of matter.
What is thermal energy
Thermal energy= releases/absorbs energy. Ex. wood burning
What is mechanical energy
-Mechanical (kinetic) energy= the energy of movement. Ex. walking
What is gravitational (potential) energy
Gravitational potential energy= the energy of position. Ex. roller coasters before a big drop
What is elastic energy
Elastic energy= the energy stored in materials as a result of their stretching/compression. Ex. a rubber band.
What is chemical energy
Chemical energy= the energy stored in bonds of atoms
=breaking/forming bonds releases/absorbs energy
Ex. breaking a glow stick, eating, digesting
What is nuclear energy
Nuclear energy
↳Nuclear fission= splitting an atom to release energy. Ex. bombs
↳Nuclear fusion= combine atoms to make energy. Ex. sun, stars
What is sound energy
Sound energy= the energy of sound waves. Ex. music, speech
What is electromagnetic energy
Electromagnetic energy
↳Electromagnetic radiation (EMR)= classified into several types according to frequency. Ex. infrared, ultraviolet.
↳Light energy= visible to the naked eye. Ex. anything visible.
What is electrical energy
Electrical energy= the flow of electrons in a circuit
