Category:Inertia (Physics)

This category contains results about inertia in the context of physics.
Definitions specific to this category can be found in Definitions/Inertia (Physics).

Inertia is the tendency of a body to maintain the same velocity in the absence of an external force, in accordance with Newton's First Law of Motion.

Equivalently put, inertia is the resistance of a body to a change in its motion.

Inertia is equivalent to mass.
