Collisional

As per the researchers, these craters are "suggestive of a violent collisional history" of the asteroid.

However, the lack of evidence does not allow for the conclusion that glacio-epochs are not associated with collisional assembly of supercontinents.

The difference is considerably lower than that of most suspected collisional satellites.

The event was brief but gentle, saving Triton from collisional disruption.

The leading, logarithmic term is frequently used, and resembles the Coulomb logarithm that occurs in other collisional plasma calculations.

The Maxwellian distribution of the rotational periods of Jupiter trojans may indicate that they have undergone a stronger collisional evolution compared to the asteroid belt.

Then the binary collision approximation is no longer valid, but rather the collisional process should be understood as a many-body process.

To probe reaction rates at molecular level, experiments are conducted under near-collisional conditions and this subject is often called molecular reaction dynamics.
