Inertia is the tendency of a body to maintain its state of rest or uniform motion unless acted upon by an external force. Inertia can also refer to: The principle of inertia is one of the fundamental laws of classical physics which are used to describe the motion of matter and how it is affected by applied forces. ...

Physics/Science

• Principle of inertia (physics), which is addressing the physics' aspects of inertia.
• Moment of inertia, also known as Rotational Inertia, is the tendency of a body to maintain its state of rest or uniform rotation unless acted upon by an external torque. This is the rotational physics equivalent of the inertia in linear physics.
• Inertia as used in automatic control refers to a property of dynamic systems, causing time delays.
• Thermal inertia, a term commonly used by engineers modelling heat transfers when referring to the volumetric heat capacity.
• Social inertia - description of a person's resistance to change in psychology and sociology.
• The tendency of an economy to continue moving in a fixed direction until a sufficient force acts to change that direction.
• One of the possible causes of Diseconomy of scale
