Examples

  • The most sophisticated future navigation systems use digital mapping, inertial guiding, and GPS signaling.

  • Why are inertial and gravitational mass the same thing?

  • It's sometimes referred to as inertial mass for this reason.

  • We're putting it through the inertial system now.

  • So this concept can lead to the design of inertial fusion energy based power plants.

  • We are losing the inertial dampeners!

  • So one can use the inertial frame as a reference to reduce the driving accelerations.

    Academic text (1999)
  • The range of scales dominated by the cascade is called the inertial range.

    Academic text (1995)
  • What is true here is that all inertial observers are equivalent with respect to all natural phenomena, meaning all natural laws.

  • The engineers designed an inertial navigation system to help the spacecraft maintain its course.

Morphology

inertial = inertia (transparent) = inert + ia + al

The adjective is a standard formation from the noun 'inertia' using the adjectival suffix '-al'.

Etymology

Inertial comes from the Latin word iners, which means 'motionless' or 'not active', and is related to the common words inert and inertia. So, inertial is used for things that resist changing their motion, especially in physics and engineering.
