a disposition to remain inactive or inert

(physics) the tendency of a body to maintain its state of rest or uniform motion unless acted upon by an external force

of or relating to inertia

a coordinate system in which Newton's first law of motion is valid

a method of controlling the flight of a missile by devices that respond to inertial forces

a system to control a plane or spacecraft; uses inertial forces

(physics) the mass of a body as determined by the second law of motion from the acceleration of the body when it is subjected to a force that is not due to gravity

a method of controlling the flight of a missile by devices that respond to inertial forces

a system to control a plane or spacecraft; uses inertial forces
