(20 cards)
Solar Nebula
A nebula cloud made from a collection of dust and gas
Gravity
It is what causes objects to have weight. When you weigh yourself, the scale tells you how much gravity is acting on your body
Fusion
The process or result of joining two or more things together to form a single entity (like welding)
Star
A fixed luminous point in the night sky which is a large, remote incandescent body like the sun
Infrared light
Infrared radiation is a type of electromagnetic radiation, as radio waves
Visible Light
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye
Ultraviolet Light
Ultraviolet light is a form of radiation which is not visible to the human eye
Matter
It is a physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
Planetary Nebula
A ring-shaped nebula formed by an expanding shell of gas around an aging star.
White Dwarf
A small very dense star that is typically the size of a planet
Red Giant
It is a very large star of high luminosity and low surface temperature
Main Sequence Star
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores
Electromagnetic Spectrum
The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies
Element
It’s a part or aspect of something abstract
Hydrogen
Hydrogen is a colorless, odorless, highly flammable gas
Helium
Helium is also a colorless and odorless gas but is also a tasteless, non-toxic, inert, monatomic gas
Proton
It is a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in size to that of an electron, but of opposite sign.
Neutron
A subatomic particle of about the same mass as a proton but with no electric charge, present in every atomic nuclei except the regular hydrogen
Nucleus
The central and most important part of an object, movement, or group, forming the basis for its activity and growth
Photon
A particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has a zero rest mass
