English term or phrase: preposition
in sentences like,
Object for experiments on (or in?) plastic collisions.
Gate for experiments on (or in?)elastic collision.

It's taken from a description of a kit for mechanical experiments.

Thank you!

... used in [in]elastic collision experiments
Explanation:
While "experiments on elastic collision" sounds acceptable, I would probably use "elastic collision experiment" instead, so the whole solution can be either "object for elastic collision experiments" or "object used in elastic collision experiments".
Depending on what this object is, "puck" or "cart" may be very appropriate.
In conjunction with "gate", I would probably prefer "used in".

As for the other, it is certainly not "plastic collision" but "inelastic collision". "Plastic" is used as the antonym of "elastic" only when it comes to deformations.

About your added comment: plastic collision sounds implausible.
In elastic and inelastic collisions alike, elastic deformations occur; the difference is that energy is lost (or rather transformed into heat) during inelastic collisions.
In a process that could be called a "plastic collision", the deformation remains. If two spherical plasticine balls collide in such a way that they are nonspherical after collision, then "plastic collision" is justified.
However, calculations are incomparably more complex (or incomplete) for such situations, so the demonstration value of such experiments is very limited compared to elastic and inelastic collisions.

Explanation:
Definitely when describing a (theoretical) field of action (or experimentation). Used in mathematics or in inelastic collisions.
Used in practice, in theory.

On the other hand for example (on): used on Earth, on the Moon, on the hand and so forth. When the localization is circumscribed to a "geographical" locus. MAu

Notes to answerer
Asker: yeah, the first phrase IS about collision with deformations. That's why I chose "plastic". Thanks.
