Tear Height is a hidden attribute that determines how far above the ground tears travel. A greater tear height effectively increases range, and a high enough tear height (around 3) can allow tears to fly over obstacles without spectral tears.

Knockback is a mechanic that determines how far an entity is pushed back by a certain force.
There are two kinds of knockback: directional and circular.
This knockback comes from Tears, most notably Isaac's. The knockback force is determined by the speed and direction of the tear, which itself is determined by Isaac's movement and stats, for example Ring Worm does not increase knockback stat but does affect knockback as the tear's speed hits extremes of very fast and very slow, hitting enemies with the fastest moment of it's arc applies significant knockback. (Needs research and confirmation)
Directional knockback affects most enemies, including bosses (except for stationary ones like Pin or Round Worm). Items (both Trinkets and Pickups) cannot be moved by tears, with the exception of bombs placed by Isaac.

Flat Worm
Isaac's tears take on an oblong appearance. They also push enemies back. increases only natural knockback and is thus nullified.
- Knockback from tears provides minor crowd control for homing enemies like flies or Gapers, increasing the time it takes them to reach Isaac.
- Be wary of the natural knockback from tears when trying to dodge charging enemies (like the smaller twin of Gemini, Gurglings, and Leeches): The tears can push them off-track and and towards the direction you are planning to escape to.
This knockback is a little shockwave that's emitted at a certain radius in all directions, most prominently from explosives, like Bombs.
Certain farts also create a (non-harmful) knockback. Some enemies, like the Fatty, can fart, and Isaac can also do so with the Butter Bean.
Pickups (including Chests) are affected by circular knockback; items, however, are not.
