General astronomy
neutron degeneracy pressure
Astronomy; General astronomy
pressure exerted by a degenerate gas made of neutrons. It is what prevents further collapse of a neutron star.
neutron star
Astronomy; General astronomy
the collapsed core for an intermediate to high-mass star. The core is more than 1.4 solar masses but less than 3 solar masses and is about the diameter of a city. The pressure from degenerate ...
newton
Astronomy; General astronomy
unit of force in the metric system. It is used to specify the amount of weight.
Newton's 1st law
Astronomy; General astronomy
(of motion): a body at rest remains at rest, and one moving in a straight line maintains a constant speed and same direction unless it is deflected by a force.
Newton's 2nd law
Astronomy; General astronomy
(of motion): the amount of force needed to cause an acceleration depends on an object's mass, such that the force applied = the mass of an object × its acceleration.
Newton's 3rd law
Astronomy; General astronomy
(of motion): for every action force ON an object, there is an equal but opposite force BY the object.
north celestial pole
Astronomy; General astronomy
(NCP): projection of the Earth's north pole onto the sky. The NCP altitude = the observer's northern latitude.
