vetävyys

Vetävyys is a Finnish noun derived from the verb vetää (to pull). It denotes the capacity to pull or draw something, and more generally the ability to attract or engage. In everyday Finnish, vetävyys can refer to the appeal or draw of a person, product, event, or idea—its ability to attract attention or participants.

In technical and engineering contexts, vetävyys describes the power to move objects by pulling or pushing, i.e., tractive force or traction. It is a key concept in vehicle dynamics, rail transport, and machinery. The available vetävyys depends on engine torque, gear ratio, wheel radius, weight distribution, and the friction between tires and the surface. When traction is sufficient, acceleration or starting from rest is possible; once tire grip is exhausted, slip occurs and effective vetävyys is reduced. Practically, engineers express vetävyys as tractive effort (TE), typically in newtons or kilonewtons.

Other related terms include vetovoima, which also conveys pulling power, and in marketing or planning contexts vetävyys captures how well something attracts attention, participants, or engagement relative to alternatives.

In summary, vetävyys is a versatile Finnish term used to describe both the physical capacity to pull or move and the broader attractiveness or draw of something in social, marketing, or practical contexts.
