Kiirendusega

Kiirendusega is the instrumental form of the Estonian noun kiirendus, meaning acceleration. It denotes the instrument or means by which an action is performed, or the manner in which something occurs. In grammar, kiirendusega is formed from the genitive singular kiirenduse plus the instrumental suffix -ga, yielding a phrase that can be translated as “with acceleration.”

Morphology and usage notes: The base noun kiirendus is a common term in physics, engineering, and everyday language when discussing speeding up or changes in velocity. The instrumental forms follow the same pattern as other Estonian instrumentals, for example kiviga (with a stone). The plural instrumental form is kiirendustega. Kiirendusega is typically used in formal or technical contexts to specify a parameter, method, or condition that involves acceleration.

Contexts and function: Kiirendusega is often found in scientific reporting, technical documentation, and analytical writing when describing motion, forces, or dynamics. It answers questions of by what means something occurs or under what rate of change a process proceeds. It can also introduce measurements, for instance indicating an acceleration value accompanying a description of movement.

Example: Masina liikumist kirjeldati kiirendusega 3 m/s². Translation: The motion of the car was described with an acceleration of 3 m/s².
