For a single particle we need 2 coordinates in a 2-D plane to specify its position and 3 coordinates in 3-D space. Thus its degree of freedom in a 3-D space is 3. For a body consisting of 2 particles (ex. a diatomic molecule) in a 3-D space with constant distance between them (let's say d) we can show (below) its degrees of freedom to be 5.
A five-dimensional space is a space with five dimensions. In mathematics , a sequence of N numbers can represent a location in an N -dimensional space . If interpreted physically, that is one more than the usual three spatial dimensions and the fourth dimension of time used in relativistic physics .
An automobile with highly stiff suspension can be considered to be a rigid body traveling on a plane (a flat, two-dimensional space). This body has three independent degrees of freedom consisting of two components of translation and one angle of rotation. Skidding or drifting is a good example of an automobile's three independent degrees of ...
The ordinary space dimensions correspond to bosonic degrees of freedom, the anticommuting dimensions to fermionic degrees of freedom. The word "superspace" was first used by John Wheeler in an unrelated sense to describe the configuration space of general relativity ; for example, this usage may be seen in his 1973 textbook Gravitation .
Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy , aurorae , planetary ionospheres and magnetospheres , radiation belts , and space weather (collectively known as solar-terrestrial physics [ 1 ] ).
astrophysics, the physics in the universe, including the properties and interactions of celestial bodies in astronomy; atmospheric physics is the application of physics to the study of the atmosphere; space physics is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System
Other degrees of freedom, such as molecular vibrational, electronic and electron spin levels are at a positive temperature, so the object still has positive sensible heat. Relaxation actually happens by exchange of energy between the nuclear spin states and other states (e.g. through the nuclear Overhauser effect with other spins).
