nonrelativity

Example:While nonrelativistic objects can be studied with classical mechanics, relativistic objects require special or general relativity to describe their behavior accurately.

Definition:A physical theory that describes how the laws of physics are the same for all non-accelerating observers and accounts for the effects of acceleration, especially the relationship between space and time.

Example:The increased mass of an electron when it is accelerated close to the speed of light is a relativistic effect that is not observed in nonrelativistic physics.

Definition:A phenomenon in physics where the effects of special or general relativity are significant, such as time dilation, length contraction, or the equivalence of mass and energy.
