Knockback

Knockback is the movement of a player, caused by an outside source.

When taking damage from any source, a player will experience an amount of knockback that generally scales directly with the power behind the attack. For example, a point-blank Scattergun blast will push its recipient farther back than an uncharged Sniper Rifle shot. While most weapons inflict minor knockback at best, there are quite a few exceptions that inflict significant knockback and can have a dramatic effect on the battlefield. Significant sources of knockback will instantly interrupt any animations the victim is in, including taunts and consumption of a lunchbox item. The only items that can reduce the effects of knockback are the Mantreads, the Quick-Fix while deploying an ÜberCharge, and the Cozy Camper.

Explosions

The explosive projectiles fired by weapons such as the Rocket Launcher and Stickybomb Launcher are among the most powerful sources of knockback and can send victims flying through the air. Crouching or being airborne reduces air drag, greatly increasing the degree of knockback experienced. Classes that utilize explosives will often take advantage of this mechanic to propel themselves great distances.

Damage over time / Self damage

Damage received from an adirectional source or a weapon that hurts the user will push the recipient upward. The degree of knockback experienced scales with the damage taken and is usually minor, but can be significant enough to access previously unreachable areas.
