Describing a framework or theory that does not take into account the effects of relativity, typically associated with classical physics.
In nonrelativistic mechanics, objects move according to Newton's laws without considering the effects of high speeds or gravitational fields.
Nonrelativistic → It is formed from "non-" (meaning not) and "relativistic" (from Latin "relativus", meaning related or relative, and the suffix "-istic" which indicates a characteristic). The term "nonrelativistic" describes a state or condition that is not related to or does not involve the principles of relativity, particularly in physics.
Think of 'not' ('non-') being applied to something that is 'related' ('relativus') to physics — this helps you remember that 'nonrelativistic' refers to concepts that do not involve relativity.
